A powerful airstrike killed 11 people in central Beirut on Saturday, the health ministry said, shaking the capital as Israel pressed its offensive against the Iran-backed Hezbollah group.

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.

Lebanese officials say Israeli airstrikes have killed at least 15 people and injured dozens in central Beirut as the once-rare strikes in the heart of Lebanon’s capital continue without Israeli warning.
