Yemen’s Houthi group said late Thursday that US warplanes launched 13 airstrikes targeting the country’s northern provinces of Sanaa, Saada and Al-Jawf. The Houthi-affiliated Al-Masirah TV channel reported that “US aggression aircraft launched an airstrike on Hamdan district in Sanaa province.”

There was no immediate comment from the American military about the joint operation, the first since President Trump took office.

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.
