The Iran-backed group, whose leader Israel killed in an air strike on Friday, said its fighters launched a “rocket salvo” at Safed and a smaller location “in defence of Lebanon and its people and in response” to Israeli attacks on cities, villages and civilians.

Hezbollah on Sunday confirmed the death of high-ranking official Nabil Kaouk in an Israeli airstrike, a day after the Lebanese militant group acknowledged the killings of multiple commanders, including longtime leader Hassan Nasrallah.

The strike on power stations and a seaport, which killed four people, was the second known time that Israel has retaliated against the militant group’s attacks by striking in Yemen.
