Israeli airstrikes have hit Yemen’s capital, days after the Iranian-backed Houthi rebels fired what the Israeli military described as the first cluster bomb they've launched since 2023.

Israeli Prime Minister Benjamin Netanyahu, speaking from the Air Force command centre in Tel Aviv, vowed to intensify operations against the Iran-backed Houthis, who have been launching missiles and drones toward Israel and attacking ships in the Red Sea for nearly two years.

The Israeli military launched a series of attacks on Yemen's power infrastructure and the presidential palace in Sanaa on Sunday, killing at least four people.
