Lebanon's health ministry said at least eight people were killed and 25 others wounded Sunday in an Israeli strike near the southern city of Sidon, where an AFP correspondent said a building was targeted.
The strike hit a densely-populated area in a Sidon suburb that saw an influx of families displaced from areas further south.
It was the first strike there since the Israel-Hezbollah war erupted last month.
"The Israeli enemy's raid on Haret Saida resulted in a... toll of eight killed," the health ministry said, revising an earlier toll of two dead.
The official National News Agency said a child was among the victims.
An AFP correspondent said one apartment was destroyed in the strike on a three-storey residential complex.
Surrounding shops and buildings were also damaged, the correspondent said, as paramedics rushed to the site of the attack to search for survivors.
The Israeli army had issued an evacuation warning for several areas in south Lebanon on Sunday, but Haret Saida was not listed among the areas to be targeted.
Also on Sunday, the Israeli military urged residents of 14 villages in southern Lebanon to evacuate immediately and move north of the Awali river.
Elsewhere in the south, a strike on Zawtar al-Sharkiya killed three people and a Saturday bombing of Marjeyoun killed five, it said.
Israel said four of its soldiers were killed in south Lebanon fighting.
Hezbollah also said it had fired a large missile salvo at the Zevulon military industries facility north of Haifa in northern Israel. Hezbollah rockets hit a house and cars and rescue crews responded to put out the fire.
One woman was seriously injured, according to Israel's ambulance service.
The war since September 23 has left at least 1,615 people dead in Lebanon, according to an AFP tally of nationwide health ministry figures, though the real number is likely to be higher due to gaps in the data.
