We're following breaking news out of Washington, DC where two Metro subway trains have collided killing at least six people and injuring at least 76 others. One of the dead was the operator of one of the trains.
The accident happened during the evening rush hour on the Red Line in the District of Columbia, near the border with Takoma Park, Maryland. We'll have the latest details on the crash.
