Iran's Revolutionary Guards said Sunday that the country's forces could fight an intense war for six months against the United States and Israel, which said it struck Tehran's commanders at a seaside hotel in the heart of Beirut.

As the conflict spilled into its second week, the regional repercussions spiraled, with Saudi Arabia intercepting a wave of drones headed for targets including the diplomatic quarter in capital Riyadh and Kuwait saying an attack hit fuel tanks at its international airport.
