The Israelis "intentionally targeted a meeting of the municipal council to discuss the city's service and relief situation" to aid people displaced by the Israeli campaign, caretaker Prime Minister Najib Mikati said.
Israel also struck at Syria's Mediterranean port city of Latakia early on Thursday, Syrian state news agency SANA reported.
Firefighters are working on extinguishing fires that had broken out, SANA added, while Syrian state television reported the country's air defenses had confronted Israeli targets over Latakia.

The U.N. mission in Lebanon (UNIFIL) said its peacekeepers observed an Israeli tank firing at their watchtower near southern Lebanon's Kfar Kela on Wednesday morning. Two cameras were destroyed, and the tower was damaged, UNIFIL said.
There was no immediate comment from the Israeli military on the UNIFIL statement.
Israel has previously called on the United Nations to move members of the UNIFIL peacekeeping force in southern Lebanon out of the combat zone for their safety.
