DUBAI -- A driver opened fire on a car driven by a U.S. citizen in northern Saudi Arabia after crashing into his vehicle, but there were no casualties, Saudi state news agency SPA reported late on Wednesday.

It was not immediately clear if the incident was a deliberate attack on the American or just a case of road rage.

"The Tabuk police received a report at around 1 p.m. (6 a.m. ET) that a car driven by a resident American citizen had been subjected to a crash and shooting from the driver of the other vehicle while driving on a road in the city of Tabuk," SPA quoted the local police chief as saying.

"There were no injuries but the car was damaged by the accident and shooting," it added.

The kingdom, a key regional U.S. ally and the world's top oil exporter, faced a campaign of attacks by al Qaeda militants targeting foreigners and government facilities between 2003 and 2006. Security forces crushed the militants, arresting and killing many and forcing others to flee the kingdom.

A man accused of killing two Japanese visitors and injuring a dozen others after crashing his car and stabbing people in a major tourist district in Guam has been arrested and faces multiple charges, police said Wednesday.

Chad Ryan DeSoto, 21, of Tamuning is accused of driving a Toyota Yaris onto a sidewalk and striking seven tourists Tuesday night at an upscale shopping area fronting the Outrigger Guam Resort in Tumon Bay, Guam police spokesman A.J. Balajadia said. DeSoto continued driving on the sidewalk, crashing into the wall of a convenience store. He then left his car and started stabbing people, police said.

DeSoto is charged with two counts of murder, 13 counts of attempted murder and 13 counts of aggravated assault, Balajadia said. No motive or other details on the investigation were released.

DeSoto was scheduled due to appear before a magistrate judge at the Superior Court of Guam on Wednesday to be formally charged.

Japan Chief Cabinet Secretary Yoshihide Suga said 14 Japanese tourists were attacked, including two who died. Two of the injured have been released from the hospital after being treated, Suga said.

Japanese media reported the dead were two women aged 28 and 82 and the survivors included an 8-month-old baby.

An official with Japanese travel operator H.I.S. Co. said eight of its customers were injured in the attack -- including some with broken bones -- but none was killed.

The wreck and alleged knife attack among high-end boutiques and hotels in Tumon Bay's Pleasure Island district sent frightened hotel guests and others fleeing for safety.

A woman at a nearby café with friends told the Pacific Daily News she saw the car plow through the driveway and into a convenience store at the resort. Ashley Quichocho, 18, of Dededo said the driver got out, ran up to bystanders and began stabbing them.

"He started stabbing someone, and I started freaking out," Quichocho said. "He was just running back and forth stabbing people."

Quichocho said she ran to the second floor of the hotel with other guests to escape.

Guam Gov. Eddie Calvo issued a statement addressed to "the people of Japan" saying the perpetrator would be prosecuted "to the fullest extent of the law." Calvo said he would increase the police presence in the visitor district.

"This was an isolated incident -- something that just doesn't happen in our community," Calvo said. "We are shocked, we are grieving with the families, and we extend our deepest condolences to those hurt."

Guam, a U.S. territory and tropical island 1,500 miles south of Tokyo, is heavily dependent on tourism -- particularly from Japan -- for its economy.

The island has a population of about 180,000 and is home to major U.S. naval and air bases. The U.S. has plans to move several thousand Marines to Guam from the southern Japanese island of Okinawa.

When German police pulled over a driver on the autobahn on Monday, they discovered his vehicle was wired up like a mobile office.

MAINZ, Germany -- Ever worry about getting caught by police using your cellphone while driving?

That was not enough of a risk for one German driver, who had an entire office installed in his FORD Mondeo station wagon.

Undercover highway police in southern Germany on Monday pulled over a 34-year-old IT specialist after he conducted an illegal passing maneuver and was going 80 miles per hour in a reduced 62-mile-per-hour zone on Germany's infamous super highway, the autobahn.

"The officers were quite surprised when they found a laptop, a printer and even a medium-size voltage transformer attached to a wood rack that was set up next to the center console," police spokesman Stephan Lassotta told NBC News.

In addition, the German highway patrol found two cellphones and a navigation system installed in the windshield of the driver's car.

"We could not prove that the driver had been using the equipment while driving, so he was not fined for that violation," Lassotta added.

But the man, who was not identified by name, was asked to store the technical equipment in his trunk immediately, before being allowed to continue his journey. German law states that "unsecured items" in vehicles are dangerous and therefore not permitted.

The man now faces a fine of more than $170 for speeding and passing traffic in a right-hand lane, in accordance with German law.
