A 47-year-old woman was killed early this morning in a vehicle accident at the intersection of 51st and Locust streets, according to reports.

The accident occurred at about 2:15 a.m. and involved two cars. The unidentified woman was the passenger in a minivan that struck another car, an SUV. The male driver of the minivan and a man and a woman in the SUV were seriously injured in the accident, according to ABC News and The Philadelphia Inquirer.

The minivan reportedly struck the SUV first and the impact was so great that the SUV flipped on the roof of a third, parked car. Rescue crews had to pry open the vehicles to extract all the passengers.

Both cars reportedly ran stop signs at the 4-way-stop at 51st and Locust.
