An Israeli air strike hit a densely-populated neighborhood in the heart of Beirut Sunday evening, killing one person and wounding nine others, according to the Lebanese Health Ministry.

Mohammed Afif was killed in a strike on the Arab socialist Baath party’s office in Beirut, according to a Hezbollah official who was not authorized to brief reporters and spoke on condition of anonymity. Afif had been especially visible after all-out war erupted between Israel and Hezbollah in September.

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 the Iran-backed group.
