Lebanese armed group Hezbollah confirmed its media relations chief Mohammad Afif was killed by an Israeli strike.

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.

Schools in Beirut were closed on Monday after Israeli strikes on the Lebanese capital killed six people including Hezbollah's spokesman, the latest in a string of top militant targets slain in the war.
