Multiple shots fired at Capitol Hill, one policeman injured

The US Capitol, seat of the Congress, was locked down today after multiple shots were fired outside one of the office buildings, injuring one policeman and sparking massive security operation.
President Barack Obama was briefed on the reports of gunfire on Capitol Hill this afternoon, according to a White House official.
"White House staff are in touch with law enforcement and monitoring the incident. Questions about the security posture at the White House complex should be directed to the United States Secret Service," the official said.
In an email, the Capitol Police wrote that gunshots have been reported on Capitol Hill requiring all occupants in all House Office Buildings to shelter in place.

"Close, lock and stay away from external doors and windows. Take annunciators, Go Kits and escape hoods; and move to the innermost part of the office away from external doors or windows," the email said.
"If you are not in your office, take shelter in the nearest office, check in with your OEC and wait for USCP to clear the incident. No one will be permitted to enter or exit the building until directed by USCP.

"All staff should monitor the situation. Further information will be provided as it becomes available," the Capitol Police said.
The incident set off a huge police response as emergency vehicles converged on the scene and security was heightened inside the Capitol, which was already tense during shutdown negotiations.

The White House was also placed in lockdown, with Secret Service agents in tactical gear deploying around the building. The security alert was later partially lifted.
According to multiple news report, the suspect is said to be a female. Law enforcement officials said there is no indication of it being an act of terrorism.
About half an hour after the incident began, the security lockdown at the Capitol was lifted and the doors reopened.
