A powerful Israeli airstrike in Beirut has killed one of Hezbollah’s key figures, Mohammed Afif. He was the media relations chief for the militant group, and his death marks a significant moment in the ongoing conflict between Israel and Hezbollah.

The Hezbollah militant group has a strong presence in central Beirut, known as the Dahiyeh, and the strikes came as Lebanese officials are considering a U.S.-brokered cease-fire proposal.

Israel killed Hezbollah’s chief spokesman in a rare central Beirut airstrike. An anonymous Hezbollah official confirmed the death of Mohammed Afif to the Associated Press, while two Lebanese security sources confirmed it to Reuters.
