People take cover as gun shoot being heard at the Capitol in Washington, DC, on October 3, 2013. The US Capitol was placed on security lockdown Thursday after shots were fired outside the complex, senators said.
"Shots fired outside the Capitol. We are in temporary lock down," Senator Claire McCaskill said on Twitter. Police were seen running within the Capitol building and outside as vehicles swarmed to the scene. AFP Photo/Jewel Samad (Photo credit should read JEWEL SAMAD/AFP/Getty Images)
