Israel has targeted central Beirut with at least four airstrikes, according to security sources cited by Reuters news agency.
Lebanon’s state-run National News Agency said the attack “completely destroyed” an eight-storey residential building in the Basta neighbourhood early on Saturday.
It is not immediately clear how many have been killed or injured and the Israeli military did not warn residents to evacuate before the attack, the fourth targeting the centre this week.
The blasts happened at about 4am (2am UK time) and came after a day of bombardment of Beirut’s southern suburbs, which Israel had warned residents of in advance.
Heavy fighting between Israel and Hezbollah is ongoing in southern Lebanon, as Israeli forces push deeper into the country since launching a major offensive in September.
US envoy Amos Hochstein was in the region this week to try to end the more than 13 months of fighting between Israel and Hezbollah, ignited last October by the Gaza war.
