North Korea fired a ballistic missile from its eastern coast toward the East Sea on Tuesday, a South Korean military official told NBC News.

The launch — one of several this year — was detected at about 9:40 a.m. local time. Additional details were not immediately available.

The launch came one day after officials in the United States, Japan and South Korea announced that they planned to ratchet up pressure on the country and its president, Kim Jong Un.

It wasn't immediately clear if this was a routine firing of a short-range missile or an attempt to perfect North Korea's longer range missiles.

A 25-year-old active duty Marine died in the hospital, three days after being struck by a vehicle while riding his motorcycle in Oceanside in a DUI crash.

According to the San Diego County Medical Examiner's Office, Nicholas Kursinskis was pronounced dead Saturday.

On June 28, at 9:24 p.m., Kursinskis was riding northbound on El Camino Real when he was struck by a pick-up truck traveling westbound on Mission Avenue. 

Kursinskis crashed into the side of the truck and was ejected from his motorcycle.

He was taken to Scripps Memorial Hospital La Jolla with multiple injuries and died three days later.

According to the Oceanside Police Department, the driver of the truck, 59-year-old Kennith Allen, was determined to be driving under the influence of alcohol.

Allen is facing a vehicular manslaughter charge.

The Trump administration on Monday night urged the court not to add more exceptions to the president's travel ban, NBC News reported.

Justice Department lawyers responded to a motion filed by Hawaii and other challengers who argued that the ban wrongly excluded grandparents and other relatives from the list of close family members who could obtain visas.

The government said the judge should only stick to the guidelines announced by the State Department on June 29: Parents, parents-in-law, spouses, fiances, children and children-in-law would be exempt from the ban on visas for travel from six mostly Muslim countries. They are Syria, Iran, Yemen, Somalia, Sudan and Libya.

A domestic violence disturbance turned into a SWAT situation Monday night after one person locked themselves inside a room in a Rancho Penasquitos home, San Diego police (SDPD) confirmed.

The incident began at 9:51 p.m. on Brome Way and Vervain Street.

Police said one other person may also be inside the home.

They believe three children may be involved but it is unclear if the children are inside or outside the home. There is a possibility of weapons inside the home.

SWAT was called out, police told NBC 7.

At this time, officers are attempting to communicate with the people in the house.

The great-grandmother of a 4-year-old boy found chained, malnourished and beaten in an apartment in Mexico says she had believed he was being raised by his father.

Virginia Sanderson told NBC 7 Monday, she was there for her grandson's birth at Palomar Hospital in Escondido. She said she even helped raise him for a while.

"Just a little sweet, innocent,” Sanderson said.

Last Tuesday, authorities rescued the boy from an apartment in Mexico City. Two people, identified as an aunt and uncle were arrested.

The boy was admitted to the hospital with multiple injuries. A photograph released by authorities showed a silver chain binding his thin legs.

"It's just not right. It's not right at all. Somebody has got do something," Sanderson said.

She added, "We have to pray for him. That's the most important thing for his safety."

She told NBC 7, her granddaughter had lost custody of the child and she thought the boy was being raised by his father in Mexico. But she saw her great-grandson's father in Escondido, just two weeks ago.

Mexico City's prosecutors believe the boy is an American citizen but the U.S. Embassy has yet to determine if that is true.

But Sanderson said she has proof.

"He's a citizen of the United States and he should be here. They had no right to send him away, out of this country. No right at all," Sanderson said.

The family knows the child is hospitalized and being treated for several injuries.

It is still unclear how he ended up in Mexico City.

Hundreds gathered at the vacant Dallas home Monday evening where the bodies of 13-year-old Shavon Randle and 19-year-old Michael Titus were discovered over the weekend, bringing a tragic end to a desperate search for the young girl.

Shavon Randle's mother, Shaquna Randle, spoke publicly for the first time since her daughter's death, visibly shaken while looking at the home where her body was discovered.[[432425173,R,300,427]]

"If y'all have kids, cherish them," Randle said. "Hold them and don't let them go, y'all. Don't let them go."

The boarded-up house is surrounded by brightly colored balloons, flowers and stuffed animals as the memorial grows.

One cousin spoke at Monday's vigil and said she had just surprised Shavon with a cell phone last week. Arrest warrant affidavits show that police tracked Shavon's phone until it was turned off, linking it to two people currently in custody.

Shavon had been living with her aunt in Lancaster, about 16 miles south of Dallas, at the time she was kidnapped, apparently taken as ransom for a drug dispute a family member was involved in but that Shavon had nothing to do with.

Her mother thanked those gathered – and those who couldn't make it.

"Thank you all for the love, the support and the prayers. I need all of that," Randle said. "She meant a lot to this family. She was like that piece."

One of Shavon's teachers, Crystal Spain, said the little girl was known for her "puffy little ponytail." Their last conversation was about how excited Shavon was to go into seventh grade this fall.

"She just wanted to live another day. Just wanted to live another day, and she can't because of some foolish people," Spain said. "It hurts. And I hurt for her mother. I heart for everybody in the community. I hurt for all of them because if you don't feel something out of this, something is wrong with you."

The vigil and march were organized by the Next Generation Action Network.

Dog owners know too well what the Fourth of July fireworks do to their pets' stress levels. Now, some in California are turning to cannabis products for pooches.

Yes, there are special treats infused with CBD (cannabidiol) — a cannabis compound — to alleviate a dog's anxiety caused by fireworks.

"I don't want him to be stressed out, especially over something as insignificant as fireworks," Bay Area pet owner Zugeiryd Garcia-Barrera said.

This year, Garcia-Barrera's dog C-Rex, will be given a new anxiety remedy: medical marijuana for pets.

At Holistic Hound in Berkeley, CBD dog treats are a big seller.

"The response has been overwhelmingly that it calms them down," said store owner Heidi Hill.

While there is THC and cannabinoids from marijuana in the treats, it's not like the pot people use, Hill said. 

"The product we sell and what makes it legal is it's from industrialized hemp," she said. "It's less than 3 percent THC — doesn't get the dogs high."

But are they safe and legal?

In December, the U.S. Drug Enforcement Administration reminded the public that CBD is considered an illegal substance, according to a research group.

Dr. Tom Hansen of San Francisco Veterinary Specialists said he has seen dogs in the ER after eating marijuana. He has not seen illness caused by the CBD products, and while pet owners tell him CBDs seem to work, he can't offer pet owners advice about them.

"We just don't know what these products are doing," he said. "There is anecdotal information, but no science behind it because it's a Schedule 1 drug. Not allowed to study it."

Experts say pet owners should read the product packaging and follow dosing directions carefully.

Thousands of fireworks will light up the San Diego Harbor on Independence Day in a spectacular show in the work for months, and a lot goes into making sure every shell goes off without a hitch. 

The planning for San Diego's Big Bay Boom started back in August and September when organizers began selecting music and pitching their project to San Diego officials. 

Sam Bruggema, Pyro Spectaculars Producer for San Diego's Big Bay Boom, says his team has been preparing the spectacular show for months. 

“It’s a big effort to get Independence Day (fireworks) for America," he told NBC 7, as his team of 28 worked behind him to put the final touches on the fireworks.

The testing began months ago when Bruggema and his team tried out the fireworks for the show, watching carefully how the firework performed in the sky. 

"Obviously it’s got to perform safely, that’s our first thing," he explained. "Once we know what it’s performance is -- it's the duration of time it lasts in the sky, the time it takes from when we launch it to the point when it breaks, that’s the most important, so it hits the beat of the music on time."

Then, once the music has been approved, Bruggema will begin to build the actual show: matching fireworks to the music. That means putting points in the show where they know they want the fireworks to break. 

"Certain music exhibits certain moods and feels, so we know there are certain types of fireworks that fit the look, the feel and the mood, and the tempo," Bruggema said.

One of the new fireworks added to this year is the quarter-quarter shell. When the firework breaks in the sky, the four quadrants of the shell will interchange colors, he said.

"Its shells like that, with the multiple color changes within the shell itself, and it’s not just your typical ball that changes colors from the inside out," he said. "It changes around the sphere."

San Diegans can expect to see thousands of fireworks light up the Harbor.

"We have 4,000 different items to pick from," Bruggema said. "It’s our pallet. We become the artists in the sky."

Bruggema said he has been working around the clock, even overcoming some local ordinances, to bring San Diegans the fireworks show.

He said it's been "really tough" to do fireworks in San Diego in recent years, and "it's going to be tougher" going forward, as officials have toughened regulations. But, Bruggema said, as a native San Diegan, he's excited to put on a show for his hometown.

"It’s a big deal, I want to perform for the people here," he said. "But it's also, well it's my town, and we want to be able to keep doing it."

As for that Big Bay Boom mishap five years ago?

Bruggema said it's "impossible" that something like that would ever happen again. His production does not use timers or delays, and each firework, with the exception of the finale, lifts on a one-to-one basis. 

"That's impossible for us, it would take hours of engineering to have that happen," Bruggema said. "With that fine system we use, it just can't happen."

"Our systems are made so they don't do that," he added.

This year's fireworks show will be set to patriotic music, with fireworks bursting from Shelter Island to Harbor Island to the Embarcadero to Seaport Village.

Archaeologists have excavated an area of Thomas Jefferson’s Monticello mansion that is believed to have been the living quarters of Sally Hemings, the enslaved woman who historians believe gave birth to six children Jefferson fathered, NBCBLK reported.

"Some of Sally’s children may have been born in this room,” said Gardiner Hallock, director of restoration for Jefferson’s mountaintop plantation in Charlottesville, Virginia. “It’s important because it shows Sally as a human being — a mother, daughter, and sister — and brings out the relationships in her life.”

Hemings' room — 14 feet, 8 inches wide and 13 feet long — went unnoticed for decades. The space was converted into a men’s bathroom in 1941, considered by some as the final insult to Hemings’ legacy.

Physical evidence shows that Hemings probably lived a higher-level lifestyle than other enslaved people on Jefferson’s plantation. Still, her room had no windows and would have been dark, damp and uncomfortable.

A 20-year-old driver struck a parked car in Pacific Beach, fatally injuring himself, San Diego police said. 

The driver, who has not been identified, was alone in his 2002 Honda Civic at the time of the crash at approximately 12:18 a.m. Tuesday. 

The man was driving eastbound on the 5100 block of Soledad Road when he struck a parked 2017 Toyota on the south side of the road, police said. 

At the time of the crash, no one was in the parked car, police said. 

When officers arrived at the scene, they broke the Honda's rear window and pulled the driver from the car, police said. 

Officers began life-saving measures, but the man succumbed to his injuries. 

The crash is under investigation. 

No further information was available. 

A Dallas-based plus-size model and student who promotes body positivity has used her social media platform to share how she fought back against a body-shamer while on a flight.

Natalie Hage, 30, said the hurtful ordeal happened on a recent American Airlines flight to Los Angeles when she only had a middle seat available to her. She had paid extra for a seat with greater leg room.

The man seated next to her "began LOUDLY huffing, sighing, and readjusting himself in his seat," she wrote on Instagram. "I see him furiously texting and then purposefully turning the phone away from me."

Hage said she noticed that the man was texting derogatory comments about her like "I think she ate a Mexican." He also wrote that he was leaving "a neck mark against the window" even though Hage was not "in his space."

"The whole flight, I wanted to disappear," she told NBC's "Today" show.

Hage captured photos of the man's texts and at the end of the flight recorded a video that shows her calmly but pointedly challenging him about his behavior.

"If I didn’t say something, I’d regret it forever," she later explained to "Today." "I’d be a hypocrite."

The man at first denied his actions then later apologized several times. Yet at one point he questioned whether she should be sitting in an emergency exit row.

In her video, Hage explains that she works out five times a week. She emphasizes that the man knows nothing about her.

"Out of the cool opportunity to get to know people in this world, you miss out on the chance to connect with another person because you decided to judge them instead," Hage told "Today."

One of San Diego's most notable and popular attractions, the historic Giant Dipper, is celebrating its 92nd birthday on the Fourth of July.

The wooden roller coaster, which officially opened to the public on July 4, 1925, is both a National and State Historic Landmark. It is also an iconic part of San Diego beach culture, located at Belmont Park in the heart of Mission Beach.

According to a Belmont Park spokesperson, the ride is one of only two remaining antique wooden roller coasters in California. It was originally built as a key attraction for the 33-acre Mission Beach Amusement Center that opened in the summer of 1925.

The entire project was the idea of sugar magnate, John D. Spreckels, a major force in San Diego's development. The original cost to build the coaster was $150,000, including the two-18 passenger trains.

The Mission Beach Amusement Center was popular through the 1930s and '40s and, in later years, it was renamed Belmont Park.

By the late 1960s, Belmont Park fell into disrepair and the park and coaster finally closed in December 1976.

In the 1980s, the Giant Dipper became an eyesore in Mission Beach and endured several problems, including several fires, peeling paint and a reputation as an encampment for transients.

After much pressure, the owner of the coaster planned to have it torn down and a demolition date was set.

According to Belmont Park reps, a group of concerned San Diegans banded together to form the “Save the Coaster Committee” in an effort to rescue the Giant Dipper from demolition.

The group succeeded in having the coaster designated as a National Landmark and requested ownership be transferred to the committee. The San Diego Coaster Company was established and $2 million was poured into restoring the ride. Restoration included all elements of the track and a new passenger train featuring six 4-person cars.

On August 11, 1990, the newly restored roller coaster reopened to the public and finally rode again.

Today, it enjoys an active life, welcoming thrill-seekers on a daily basis who dare to take its dips, twists and turns. The top of the coaster offers some breathtaking views of Mission Beach and the ocean.

According to the Roller Coaster Database website, the coaster spans 2,600 feet in length and has a height of 73 feet. It travels at 55 mph, with each ride lasting a little more than two minutes.

Riders must be at least 50-inches-tall to enjoy the Giant Dipper fun and each ride costs $6, though some Belmont Park ticket packages do include unlimited rides on the iconic coaster.

The popular beach community it calls home spans nearly two miles of ocean front views and boasts a boardwalk frequented bicyclists, joggers and casual strollers. Along the boardwalk, dozens of eateries and small shops offer snacks and trinkets, and a wall offers a relaxing place to rest and gaze out at the ocean.

Loading up the family and heading out to the fireworks stand, you might have fielded this question a time or two from an inquisitive toddler: why do we shoot off fireworks every Fourth of July? 

The tradition spans centuries, dating back to the very first celebration of America's independence.

The Massachusetts Historical Society even found an old letter from John Adams to Abigail Adams the day before the signing of the Declaration of Independence, envisioning what he hoped the celebrations would become in the years to come.

"It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more," Adams wrote to his wife on July 3, 1776.

And sure enough, the star-spangled day's fiery tribute spread like wildfire.

James Heintze, the author of "The Fourth of July Encyclopedia," resurfaced some of the earliest reports of gunpowder being shot during celebrations on July 25, 1776. The Virginia Gazette described crowds gathering in Williamsburg for a military parade with the firing of cannon gunpowder.

One year later, 13 fireworks were shot high above the city of Philadelphia to commemorate the anniversary.

"About noon all the armed ships and gallies in the river were drawn up before the city, dressed in the gayest manner, with the colours of the United States and streamers displayed," the Virginia Gazette wrote on July 4, 1777. "At one o'clock, the yards being properly manned, they began the celebration of the day by a discharge of thirteen cannon from each of the ships, and one from each of the thirteen gallies, in honour of the Thirteen United States."

And the rest is history.

Today, firework shows are a central part of Fourth of July celebrations in cities and towns across America.

As big crowds pack San Diego's beaches to celebrate Independence Day Tuesday, lifeguards have reminded beachgoers to watch out for stingrays.

Tens of thousands of people flock to the coast for the Fourth of July, which is typically the busiest beach weekend of the year.

One of the biggest concerns for lifeguards are the stingrays. Lifeguards say beachgoers should shuffle their feet while walking in the water to scare them away.

"Now that the water is warmer, we're seeing a lot more stings," said Tyler Grant, a senior lifeguard in Del Mar.

Del Mar lifeguards say they've had more stings, with an average of 10 to 15 a day.

San Diego lifeguards say it's normal to see a couple stingrays a day. The amount increases when the water is warm and surf is small.

The beaches are packed and campsites have been booked for months. Lifeguards say finding parking spots by the beach at this point is near impossible.

"It's been insane for parking and we've had to shut down a few times, but everyone has been really good about it, everybody has a great attitude and looks like a lot of fun," said Shane McKillip, a parking valet working at Poisedon in Del Mar.

Del Mar is one of the most crowded areas in San Diego. Lifeguards expect roughly 17,000 people at this beach alone this holiday weekend. The lifeguard staff has nearly doubled.

"We're all prepped and ready assuming people have called in sick and taken an extra vacation day, so we're fully staffed with 35 lifeguards, open 8 [a.m.] to 8 [p.m.] today," said Grant.

Last year, more than 250,000 people packed the beaches in San Diego for Independence Day, according to the San Diego Lifeguards.

The campground at Carlsbad state beach has reached capacity, according to campground officials. Online reservations that opened seven months in advance were sold within seconds.

Solana Circle will be closed to vehicle traffic this Fourth of July from 8:00 p.m. to approximately 10:00 p.m.

The streets will be closed at the intersection of Solana Circle and Via de la Valle and East Solana Circle and Nardo Avenue.

No vehicles will be allowed to access or exit Solana Circle or attached driveways between these times.

Please make advance plans if you must utilize your vehicle during that time or plan to view the fireworks at that location.

Any person in the area should be prepared to move if an emergency vehicle needs access.

Boating under the influence, or boating while intoxicated, is just as deadly as drinking and driving, warns the San Diego Coast Guard.

Coast Guard units throughout the San Diego area are scheduled to increase boating safety patrols in an intensified nationwide effort, in support of “Operation Dry Water,” to enforce boating under the influence laws.

Operation Dry Water is aimed at raising awareness of the dangers of operating under the influence in an effort to decrease the number of recreational boating accidents and deaths.

It is illegal to operate a boat while under the influence of alcohol or drugs in every state. Penalties for violating BUI/BWI laws can include large fines, suspension or revocation of boat operator privileges and jail terms.

Boaters can expect increased presence from the Coast Guard and law enforcement partners through the weekend and Fourth of July holiday. There will be dockside safety equipment inspections and boating safety boardings on the water to raise awareness.

“We’re very fortunate in San Diego to have such amazing recreational opportunities on the water,” said Commander Rob Potter, Chief of Response and Air Operations at Coast Guard Sector San Diego.

“The key is we want people to enjoy those opportunities safely. Much like drinking and driving, boating under the influence dramatically increases the risk that a good time can take a tragic turn.”

California has the third largest number of recreational boats in the country and has the second highest number of boating-related accidents and deaths according to the Coast Guard’s 2016 statistics.

Nationwide, 624 people died in boating and paddling accidents in 2016. Approximately 80 percent drown, and more than 83 percent of those people were not wearing a life jacket.

Alcohol use is the lead contributing factor in fatal boating accidents accounting for nearly 15 percent of all reported fatalities.

Below are some other tips from the Coast Guard to help boaters have a safe and pleasant weekend on the water:

• Make sure a friend or relative knows your float plan. A float plan states where you are going and how many people are on board your vessel. It also gives a vessel description, details your destination and what time you expect to arrive there. If you are delayed for some reason, make sure you let someone know.
• Make certain to check the local weather prior to departing the dock. Weather can change very rapidly and you should keep a watchful eye on the fore-casted conditions.
• Have nautical charts of the area you are boating in, a global positioning device and a reliable means of communication on board your vessel. VHF-radio is the best method of communication while on the water. Although cell phones are a good backup, they can be unreliable due to gaps in coverage area and the inevitable dead battery.
• Wear your life jacket. More than 83 percent of boaters who drown were not wearing their life jackets. In an emergency there might not be enough time to put one on, so wearing one at all times may save your life.
