At least 11 people have been killed and several others injured after an Israeli strike flattened a multi-story residential building in central Beirut overnight, Lebanese officials said. Israel has been escalating its attacks on the Lebanese militant group Hezbollah despite ongoing ceasefire efforts.

The attack was the third strike in the Lebanese capital this week, part of a wave of amped-up Israeli military activity across the country.

BEIRUT − Lebanon and the militant group Hezbollah have agreed to a U.S. ceasefire proposal and made some comments on the content, a top Lebanese official told Reuters on Monday, describing the effort as the most serious yet to end weeks of fighting and Israeli bombardments.
