Police near the U.S. Capitol opened fire on Thursday on a car being chased by authorities from near the White House, hitting a woman driving the vehicle that also contained a child, an intelligence source told CNN.
The child was escorted away from the scene and appeared to be uninjured.
The gunfire erupted near the heart of the U.S. government and brought a swarm of emergency vehicles and caused Congress and surrounding offices to be temporarily locked down.
Police also closed Pennsylvania Avenue in front of the White House.
The FBI dispatched units in response to reports of shots near Garfield Circle, which is on the Senate side of the Capitol.
Capitol Police said an officer injured in the incident was hurt in a crash.
House and Senate sessions were immediately suspended.
A Capitol Police bulletin said reports of gunshots required "all occupants in all House office buildings to shelter in place." Authorities later lifted the lockdown.
Officials say there is no indication of any link to terrorism and that this appears to be an isolated incident involving the lone vehicle.
