The number of dead was not immediately known.
The warplanes hit Taibeh, about 5 kilometers (3 miles) from the Israeli border, destroying a house where 17 people had taken refuge.
The second attack flattened a building in Aita al-Shaab, 2 kilometers (1 mile) inside Lebanon. Fifty people were reported covered in the rubble there.
Earlier on Friday security sources in Lebanon said at least 33 farm workers, including many Kurds and Syrians, were killed when Israeli aircraft bombarded trucks being loaded with fruits at a farm on Lebanon's border with Syria.
They said the farm was near the village of Qaa in the northern tip of the eastern Bekaa Valley. Aircraft fired at least three rockets at the trucks which were being loaded with peaches and plums.
