The UN's Jan Egeland has condemned the devastation caused by Israeli air strikes in Beirut, saying it is a violation of humanitarian law.
Mr Egeland, the UN's emergency relief chief, described the destruction as "horrific" as he toured the city.
He arrived hours after another Israeli strike on Beirut. Israel also hit Sidon, a port city in the south crammed with refugees, for the first time.
In Haifa, two people were killed amid a volley of rockets on the Israeli city.
Fifteen people are reported injured by the rockets, launched by Hezbollah militants over the border with Lebanon.
The BBC News website's Raffi Berg visited the scene of one of the rocket attacks in northern Haifa.
