The first apparent Israeli airstrike on central Beirut in nearly a year of conflict levelled an apartment building early Monday. It came after Israel hit targets across Lebanon and killed dozens of people, as Hezbollah sustained heavy blows to its command structure, including the killing of its leader, Hassan Nasrallah.

The airstrike hit a residential building, according to an Associated Press journalist at the scene. Videos showed ambulances and a crowd gathered near the building in a mainly Sunni district with a busy thoroughfare lined with shops.
