Seven killed in Washington subway crash: mayor

WASHINGTON (Reuters) - Seven people died when two subway trains collided during the Monday afternoon rush hour in the worst rail accident in Washington, D.C.'s history, Mayor Adrian Fenty said on Tuesday.

A D.C. Fire Department official had earlier told Reuters that nine people died in the crash, when one train hit another that had stopped on above-ground tracks on the outskirts of the city.

Roughly 75 passengers were involved in the accident, Fenty said. Two patients had been in critical condition, but the condition of one of them was upgraded overnight, he said at a morning press conference near the scene of the accident.
