The United States Capitol was placed on lockdown Thursday afternoon after shots were fired in the vicinity of the chamber. At least one Capitol Police officer was injured, officials said.
The FBI was responding to the scene, and a helicopter landed in front of the Capitol. A message from the Capitol Police ordered anyone in a House office to “shelter in place.”
“Close, lock and stay away from external doors and windows,” the message said.
