US capital goes from shutdown to lockdown
Capitol building 'attack' sparks alert; calm returns later to quieter city
The United States capital has been quieter than usual since the government shutdown.
But not so on Thursday - the third day of the stand-off over government funding - as attention diverted from the shutdown to a lockdown temporarily.
Just after 2pm here, police swarmed the Capitol building and the White House after a woman rammed a security barricade, then led the authorities on a high-speed chase.
About half an hour later, the woman was shot dead and the authorities subsequently found a one-year-old child in the black Infiniti sedan she was driving.
