U.S. President Donald Trump offered condolences Saturday to the U.K. for a deadly knife attack in London.

Trump spoke to British Prime Minister Boris Johnson via telephone, said White House spokesman Judd Deere in a statement.

“The two leaders look forward to meeting with one another at the upcoming NATO Leaders Meeting in the UK,” said Deere.

Authorities identified Usman Khan, 28, a “convicted terrorist” who resided in the Staffordshire area, as being behind the London Bridge attack that claimed two lives and injured three others Friday.
