Yemen's Houthi rebel movement has confirmed that its self-proclaimed Prime Minister Ahmed Ghaleb Nasser al-Rahawi was killed in Israeli air strikes earlier this week.

The Iran-backed group said several other senior officials were killed when the Israel Defense Forces (IDF) targeted Yemen's capital, Sanaa, on Thursday.

The IDF said at the time that it attacked a Houthi "military target" in the Sanaa area, giving no further details.

The Houthis have controlled much of north-western Yemen since 2014, after ousting the internationally recognised government from Sanaa and triggering a devastating civil war.

The Houthis said Rahawi had been killed alongside several Houthi ministers, though it did not name the others.
