The head of Hezbollah's media relations, Mohammad Afif, was killed Sunday in an Israeli strike that targeted a building in a densely-populated neighborhood in Beirut.

An Israeli strike on a building in central Beirut on Sunday killed Hezbollah's media relations chief Mohammad Afif, two Lebanese security sources told Reuters, though there was no immediate confirmation from 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.
