A military statement said Israeli forces "struck... deep inside Yemen, targeting an energy infrastructure site that served the Huthi terrorist regime" in the area of the rebel-held capital, without naming the site.

The Huthis' Al-Masirah TV, citing a civil defence source, reported "an aggression targeting the Haziz power station" south of the city.

There were no immediate reports of casualties.

A photographer working with AFP reported significant damage at the site.

An employee of the power station told AFP that "two aggressive strikes by the Israeli enemy" hit the site in the early morning, but there were no casualties.

Since the October 2023 start of the Israel-Hamas war in the Gaza Strip, the Huthis have repeatedly fired missiles and drones at Israel, claiming to be acting in solidarity with the Palestinians.

Most Huthi attacks have been intercepted, but have prompted Israeli air strikes on rebel targets in Yemen.

The military said its latest "strikes were conducted in response to repeated attacks" by the Huthis.

On Sunday afternoon, the Israeli military said it intercepted another missile fired from Yemen, after sirens went off in several regions.

Defence Minister Israel Katz said in a post on X that the Huthis would "pay with compound interest for every attempt to fire at Israel" and that Israel was "imposing an air and sea blockade" on the group.

In June, Katz threatened a blockade, without any notable follow up.

Beyond attacks on Israel, the Huthis have also targeted ships they say are Israeli-linked in the Red Sea and Gulf of Aden off Yemen.

The Iran-backed group broadened its campaign to target ships tied to the United States and Britain after the two countries began military strikes aimed at securing the waterway in January 2024.

In May, the rebels cemented a ceasefire with the United States that ended weeks of intense US strikes, but vowed to continue targeting Israeli ships.
