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.

The United States intensified strikes on Yemen's Iran-backed Houthis this year to stop attacks on Red Sea shipping, but rights activists have raised concerns over civilian casualties.

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