An Israeli drone strike hit a neighbourhood in central Beirut on Monday, a Lebanese security source said, the second day in a row that a target within the Lebanese capital has been struck as Israel presses its campaign against the Iran-backed Hezbollah.

The strike in a densely populated residential area comes following reports that the U.S. envoy has delayed his visit for ceasefire talks.

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