At least 10 strikes hit the southern suburbs before dawn after the Israeli military issued evacuation warnings, with AFPTV footage showing explosions and clouds of smoke.
Israel this week issued a citywide evacuation order for the first time since it stepped up its attacks on Lebanon in late September.
The strikes in Beirut came after Israel's prime minister met US officials to discuss a possible truce deal for Lebanon.
Despite growing pressure from the United States and others in the international community for a cease-fire in the fighting in Gaza and Lebanon, Israeli strikes against the militant Hezbollah group are increasingly expanding beyond Lebanon's periphery.
