LONDON: A man was arrested after a car collided with security barriers outside London's parliament building and a number of pedestrians were injured, police said on Tuesday (Aug 14).
Police said none of the injuries were life-threatening and they could not immediately determine whether the incident was terrorism-related.
"The male driver of the car was detained by officers at the scene. A number of pedestrians have been injured. Officers remain at the scene. We will issue further info when we have it," London's police force said in a statement on Twitter.
Footage on social media showed heavily-armed police response units arriving at the scene, with the area outside the parliament building in central London sealed off.
Police said they could not immediately say whether it was a terrorism-related incident or not.
"We're still trying to piece it together," a spokeswoman said.
"Someone driving towards parliament at speed, it wasn’t a normal, it’s not a minor like accident, it’s not like a road traffic incident," witness Jason Williams told Sky News. "This is something in my opinion planned and very serious."
Media reports said a cyclist was among the injured.
Armed police immediately surrounded the silver car after it crashed at 7.37am (06:37 GMT), pointing guns at the driver as he was removed from the vehicle, according to footage posted on Twitter.
Later images showed police holding the man, dressed in jeans and a black puffer jacket, in handcuffs as roads around parliament were sealed off.
Westminster Underground station, close to parliament, was closed and the building cordoned off. No one was being allowed entry to parliament. As parliament is in recess for summer, most lawmakers are not using the building.
In March 2017, Khalid Masood, 52, killed four people on nearby Westminster Bridge before he stabbed to death an unarmed police officer in the grounds of parliament. He was shot dead at the scene.
It was the first of five attacks on Britain last year which police blamed on terrorism.
Britain is on its second highest threat level of "severe", meaning an attack by militants is considered highly likely.
Last week, a Muslim convert admitted plotting to kill more than 100 people by driving a truck into pedestrians on London's Oxford Street, the capital's major shopping thoroughfare.
