Britain’s military launched airstrikes against Houthi targets in Yemen on Tuesday with US forces, its defense ministry said – the first public acknowledgment of a joint operation since the Trump administration escalated the US campaign against the militant group.

Yemen's Houthi rebels say a U.S. strike has hit a detention center for migrants in Saada, killing dozens of people.

The Houthi militia, which is backed by Iran, said the attack was an American strike. The U.S. Defense Department said it was assessing the claims and took them seriously.
