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.

The spokesperson of the Lebanese militant group Hezbollah, Mohammed Afif, was reportedly killed in an Israeli strike on Beirut on Sunday.

The latest in a series of targeted killings of senior Hezbollah officials came as Lebanese officials were considering a United States-led cease-fire proposal.
