Six people were killed Friday in two separate accidents near the Interstate 35 and Interstate 40 interchange in Oklahoma City, including five in an early-morning crash.
None of the victims' names were released because their relatives had not yet been informed of their deaths, authorities said.
The five-fatality crash occurred about 1 a.m. when a car and a tractor-trailer rig collided in the southbound lanes of I-35 just south of I-40.
Oklahoma Highway Patrol troopers said the car was southbound on I-35 when it left the road, then returned and went under the truck, shearing the roof off the car.
The car then spun onto the westbound lanes of I-40 as it caught fire, said Capt. Chris West, patrol spokesman. He said all five people in the car were killed. All five were thrown out of the vehicle. The truck driver was not injured.
The crash forced the closure of the eastbound and westbound on-ramps from I-40 to southbound I-35 for much of the morning.
Four of the five victims were foreign nationals from India, West said.
