At least 20 people were killed in a powerful Israeli strike that flattened a multi-storey building in densely populated central Beirut, Lebanese officials said on Saturday, as more deaths were reported from Israeli attacks in eastern Lebanon.

The strikes at 4 a.m. destroyed an eight-story building in central Beirut and left a crater in the ground. Also on Saturday, a drone strike killed two people and injured three in the southern port city of Tyre, according to the state-run National News Agency.
