Lebanon’s capital city is returning to a cycle of violence and destruction just as it was beginning to stabilize after years of chaos.

The Lebanese militant group captured an advanced Israeli anti-tank missile in the 2006 war, and its ally, Iran, reverse-engineered it, Israeli officials say.

A powerful Israeli air strike flattened a residential building in central Beirut early Saturday, killing at least 11 people and wounding 63 others, according to witnesses and the Health Ministry's initial count.
