Emergency personnel stand near a police car after gunshots were fired outside the U.S. Capitol building in Washington, October 3, 2013. The U.S. Capitol was in lockdown on Thursday after gunshots were fired outside the building, injuring several people including a law enforcement officer, a Senate aide and a Capitol police officer said. The U.S. House of Representatives and Senate were in session when the gunshots were heard. The U.S. government was partially shut down this week when lawmakers failed to agree on a budget.
