Woman Shot After Chase at U.S. Capitol

A woman was shot, a police officer was injured and the U.S. Capitol and neighboring government buildings went into lockdown Thursday afternoon after gunshots were fired on Capitol Hill following a high-speed car chase from the White House.

The officer was injured when his cruiser was struck by a woman fleeing police in a late-model black car, apparently with a child inside, police said.

This is what's known so far:

• The chase began at a checkpoint to get onto the White House grounds and ended about 2:20 p.m. outside the Hart Senate Office building with the shots fired. 
• One U.S. official said a woman was killed after she tried to ram through barricades near the White House, but her death could not be confirmed.
• No members of Congress or their staff were injured. This is not believed to be a terrorist incident.
