LONDON — British Prime Minister Boris Johnson said that the Iranian general killed in a U.S. drone strike in Iraq was “a threat to all our interests” and that “we will not lament his death.”

Johnson, who spoke with U.S. President Donald Trump on Sunday, called for de-escalation from all sides.

“All calls for retaliation or reprisals will simply lead to more violence in the region and they are in no one’s interest,” the U.K. leader said.

It was the first statement from Johnson on soaring Mideast tensions since Iranian Gen. Qassem Soleimani was killed in Baghdad on Friday.
