More than 320 people, mostly civilians, have been killed and hundreds injured since the start of Israel's offensive in Lebanon.
Israeli warplanes dropped 23 tonnes of bombs on a bunker in south Beirut where senior Hezbollah leaders were thought to be, including the leader of Hezbollah, Hassan Nasrallah.
Israeli military officials said the bunker was in the Bourj al-Barajneh section of southern Beirut.
Israel has said that one of the objects of its offensive in Lebanon is to eliminate Hezbollah leaders.
Hezbollah later said that none of leaders or members were killed in the raid although they didn't mention possible injuries.

Christian neighbourhood hit
Israeli fighter bombers also targeted Hezbollah's "security perimeter" in Beirut's mainly Shiite southern suburbs. The zone, where the group once maintained its headquarters, has been flattened in previous raids in the past week.
Israeli jets also raided two military bases of a pro-Syrian Palestinian radical group in eastern Lebanon, police said.
There were no reports of casualties from the three raids on the bases of the Popular Front for the Liberation of Palestine-General Command (PFLP-GC) in Sultan Yaacub, where the Syrian-backed group maintains a network of underground tunnels.
Israeli helicopters also fired four rockets on a residential Christian neighbourhood of central Beirut, the first direct strikes in the heart of the Lebanese capital, but there were no casualties.
Rockets hit a piece of water-bore drilling equipment in a parking lot behind a police station in the eastern district of Ashrafiyeh.
Israeli forces have been targeting trucks in various parts of Lebanese regions since Israel launched a massive offensive after Lebanon's Shiite militant Hezbollah group captured two soldiers on July 12.
In Israel, a military spokesman said Israeli aircraft struck 12 roads linking Syria to Lebanon to prevent arms shipments and fighters to Hezbollah in the south of the country.
The warplanes also struck four bridges in a region neighbouring Syria in northern and eastern Lebanon, police said, without giving an immediate casualty toll.
