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.

The strikes, which destroyed an eight-story building and left a crater in the ground, were the fourth in Beirut in less than a week.

Israel was targeting a senior Hezbollah commander, but failed to kill him, one Israeli official said. Hezbollah officials said none of the group’s leaders were at the attack site.
