The Israeli military has warned people to evacuate from more areas of southern Lebanon, including a built-up Palestinian refugee camp.
Israeli airstrikes, meanwhile, killed at least eight people in different parts of the country on Thursday.
The Rashidiyeh refugee camp near the port city of Tyre is one of several dating back to the 1948 Mideast war, when hundreds of thousands of Palestinians fled or were driven out of what is now Israel.
Israel invaded Lebanon at the start of October, after nearly a year of trading fire with Hezbollah.
Iran backs both groups.
Israel has warned people to evacuate from large areas of the country, including major cities in the south and east. More than a million people have already fled their homes.
Israeli strikes killed seven people in eastern Lebanon, according to Lebanon’s state-run National News agency. Another strike killed a man on a motorcycle on the coastal highway between Tyre and Sidon.
The news agency also reported a strike on a car on a main highway running through the mountains outside the capital, Beirut.
It said the strike closed the highway, diverting traffic through nearby villages. There was no immediate word on casualties.
