       WASHINGTON--Two Washington, D. C. subway trains collided during the Monday afternoon rush hour, killing six people and 70 in a mass of tangled metal.

Mayor Adrian Fenty called the crash the deadliest in the 33-year history of the city's Metro subway system.

Fire Chief Dennis Rubin said 70 people had been treated for injuries, including at least two who were critically injured.

       At least one car from one of the trains was hurled onto the top of the other train in the accident, which occurred on above-ground tracks.

Emergency workers propped ladders up against train doors to rescue people.

Officials said one train hit another train that had stopped, but the cause of the crash was not immediately clear.

       It happened on the heavily traveled red line at 5 p.m. EDT, between Fort Totten and Takoma stations on the northeastern outskirts of the city near the border with Maryland. Both trains were heading south into the city.

       It was the first crash involving a passenger death since 1982, when three people were killed in a derailment. The Metro train system began service in 1796.
