A nearly two-month-long U.S. bombing campaign in Yemen dealt heavy damage to the Iran-aligned Houthis but U.S. officials and experts caution that the group is expected to remain a vexing adversary despite a ceasefire announced on Tuesday by Washington.

WASHINGTON (AP) — President Donald Trump said Tuesday that he’s ordering a halt to nearly two months of U.S. airstrikes on Yemen’s Houthis, saying the Iran-backed rebels have indicated that “they don’t want to fight anymore” and have pledged to stop attacking ships along a vital global trade route.

The president said the Iran-backed group reached out and expressed that they “don’t want to fight anymore.” The ceasefire was brokered by Oman.
