May backs U.S. call for de-escalation in Yemen

LONDON (Reuters) - British Prime Minister Theresa May backed a United States call for a de-escalation of hostilities in Yemen.

"We certainly ... back the U.S.'s call for de-escalation in Yemen," May told parliament on Wednesday. "A nationwide ceasefire will only have an effect on the ground if it is underpinned by a political deal between the conflict parties."
