Israel struck multiple targets in Yemen it said were controlled by Houthis, the last of the Iran-backed groups still fully engaged in the regional war that began 14 months ago.

The Israeli military said the airstrikes targeted infrastructure that the Houthis have used to bring Iranian weapons and officials into Yemen.

Israeli forces unleashed a series of strikes on the Yemeni capital Sanaa and the western city of Hodeidah on Thursday, according to Houthi-run media, killing at least four people and injuring more than a dozen others.
