An official says the Yemeni group will not stop until the war in Gaza ends, as Israel's PM says it is "just getting started".

Israeli forces unleashed a series of strikes on the Yemeni capital Sanaa and the western city of Hodeidah on Thursday, killing at least six people and injuring dozens more, the Houthi militant group said in a statement.

The Houthis have ramped up their attacks on Israel, while Israeli leader Benjamin Netanyahu says the fight against the militant group “is only getting started.”
