22 killed in airstrikes in Beirut

The air raid on central Beirut is reportedly the deadliest in over a year of war

Israeli airstrikes on central Beirut on Thursday left two neighborhoods smoldering, killed 22 people and wounded dozens, Lebanon's health ministry said, as well as further escalating Israel's bloody conflict with Iran-backed Hezbollah militants in Lebanon.

The air raid on central Beirut - the deadliest in over a year of war - apparently targeted two residential buildings in separate neighborhoods simultaneously, according to an AP photographer at the scene. It brought down one eight-story building and wiped out the lower floors of the other.

The Israeli military said it was looking into the reported strikes. After the strikes, Hezbollah's Al Manar TV reported that an attempt to kill Wafiq Safa, a top security official with the group, had failed. It said that Safa had not been inside of either of the targeted buildings.

Thursday's strikes followed a year of tit-for-tat exchanges between Hezbollah and Israel that boiled over into all-out war in recent weeks, with Israel carrying out waves of heavy airstrikes across Lebanon and launching a ground invasion.
