An Israeli airstrike killed the prime minister of the Houthi rebel-controlled government in Yemen’s capital, Sanaa, the Houthis said on Saturday. Ahmed al-Rahawi was the highest-ranking Houthi official to be killed in the Israeli-U.S. campaign against the Iranian-backed rebels, news agency AP reported.

Al-Rahawi was killed in Thursday’s strike in Sanaa along with several ministers, the Houthis said in a statement. Other ministers and officials were wounded, the statement added, without providing further details.

The Houthi statement said the prime minister was targeted along with other members of his government during a “routine workshop held by the government to evaluate its activities and performance over the past year”, reported AP.
