>> An assailant has been shot and dozens of people have been injured at an incident in Central London. I'm Reuters reporter Mia Womersley in front of the houses of Parliament, where people have reported hearing gunshots and seeing dozens of people lying injured on a bridge. A Parliamentary official earlier said that two people have been shot.
The House of Commons was shut down, the session has been suspended, and there are reports that Theresa May is safe. A Reuter's reporter inside the Houses of Parliament said medical staff are treating two people, whilst the session was suspended. And the nearby tube station, Westminster tube station, has been closed down.
A Reuters photographer said that he saw dozens of people lying across the length of the bridge. There's been some speculation that maybe a car was involved, because they didn't hear any gunshots there on that bridge, although some were reported to have been heard by MPs inside the House of Commons.
British security sources say the motivation of the attack is still unclear, but they are saying they're treating it as a terrorist incident until they know otherwise. Police believe also there's a suspect vehicle outside Parliament and police have evacuated the area. This area of London is of course one of the prime tourist hotspots.
We've got Big Ben, the Houses of Parliament. Police have cordoned off the area behind me and keep pushing us further and further away from the scene of the incident, and the London Eye has also been stopped.
