Scores were killed and injured in an Israeli airstrike that targeted at least one senior Hezbollah figure in central Beirut on Thursday, security sources said.
A large fire blazed in the background as rescue workers used hand torches to search through the rubble for survivors.
It was not clear who the Hezbollah targets were. The neighborhood was not previously hit by Israel.
A thick column of smoke rose above central Beirut after what appeared to be Israel's latest major aerial attack in a widening offensive against Hezbollah.
"The Israeli enemy launched a strike in Beirut, targeting a building near the Khatam al-Anbiya complex in Nuwayri, with another strike targeting the Ras al-Nabaa area near the al-Amiliyah building," the National News Agency said.
At least 11 people were killed and 48 injured in a preliminary toll of the Israeli attacks, Lebanon's health ministry said in a statement.
