The British Parliament is in lockdown after a shooting incident there, reports the BBC. A police officer was reportedly stabbed after a vehicle ran several people over on nearby Westminster Bridge. Metropolitan police say they are presumptively treating it as a terrorist incident "until we know otherwise."

BBC Radio 5 reports that "around three shots" were heard after a man ran at the gates of the parliamentary compound, armed with a knife.

It's not clear if there were two separate assailants. The obvious assumption taking hold on social media is that the driver of the car was also the attacker in Parliament Square. https://twitter.com/thepatrickdaly/status/844561414907985922
