Parliament is on lockdown after an attack in Westminster

A man has been shot and parliament is on lockdown after an attack at the Palace of Westminster. Several people have also been run over on Westminster Bridge.

Details are sparse. But according to eyewitness reports, the car ploughed into people on the bridge before crashing into railings that surround the Palace of Westminster. A man then entered Old Palace Yard – the entrance used by MPs and usually heavily guarded. The man stabbed a police officer and ran into the yard. He was confronted by armed police who shot him.

The BBC is reporting that one woman has died. The police are saying they are treating it as a “terrorist incident” until they know otherwise:

But very few details are currently known. And these tweets provides a timely reminder for people watching the unfolding coverage:
