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.

Israeli forces unleashed a series of deadly 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.

JERUSALEM (AP) — A new round of Israeli airstrikes in Yemen on Thursday targeted the Houthi rebel-held capital of Sanaa and multiple ports, while the World Health Organization’s director-general said the bombardment occurred nearby as he prepared to board a flight in Sanaa, with a crew member injured.
