Donald Trump has condemned the London Bridge Terror attack as a “horrific act of violence” - and pledged support to the UK.
The American president’s statement came after a terror attack unfolded in London Bridge on Friday afternoon.
The attack left one person dead, as well as several with knife injuries.
The suspect, who was shot dead at the scene by police, was believed to have been wearing a hoax explosive device.
Mr Trump has been briefed on the situation, a White House official said.

Prominent Trump campaigner David Wohl has sparked controversy for comments over the latest terror attack in London.
He write: “If law-abiding Londoners could carry firearms legally, it probably wouldn't have happened.
"Amazing how bold the terrorists are when they know their victims will be unarmed."
