Israel and Hezbollah indicated they were clashing deeper inside Lebanese territory. An escalation could undermine efforts to reach a cease-fire, as Iran’s leader signaled he supported ending the war with Israel.

A senior Lebanese official has signalled that Hezbollah is ready to pull its forces away from the Lebanese-Israeli border in any ceasefire, while rejecting Israel's demand for freedom to act against the Iran-backed group in Lebanon in the future.

The Israeli military attacked the southern suburbs of Beirut, seen as a stronghold of Lebanese Shiite militia Hezbollah, with at least four airstrikes on Thursday, according to a dpa reporter who witnessed them.
