Israel struck southern Lebanon and Beirut early Sunday, killing 12, the Lebanese Health Ministry reported, as the Middle East conflict intensifies. Israeli officials said the strikes targeted commanders of the Lebanese branch of Iran’s Revolutionary Guards’ Quds Force, following Prime Minister Benjamin Netanyahu’s promise of “many surprises” in the next phase of the war.

In the Gulf, two Kuwaiti border guards were killed when missiles and drones hit the country. On Saturday, an Israeli strike on an oil storage facility in Tehran sent pillars of fire into the night sky, marking the first reported attack on a civilian industrial site during the conflict.
