A 13-year-old boy died and another boy, 8, is in grave condition after they were trapped Thursday in a vehicle that was submerged in the harbor, authorities said.
Two adults were also in the car; all four people were rescued by firefighters and a diving team from the Los Angeles Fire Department, according to authorities.
About 6:10 p.m., the fire department was alerted to a vehicle submerged in the water at Berth 73 in the Port of Los Angeles, said fire department spokesman Brian Humphrey.
Two adults managed to escape from the vehicle, and divers had to rescue the two children who were trapped underwater, authorities said.
All four were transported to a hospital.
The vehicle was estimated to be about 30 feet underwater, Humphrey said.
Divers continued surveying the area around the vehicle as a precaution, he said.
