A statement from Lebanon's Health Ministry said at least 15 people were injured - including three children - in an attack on a southern Lebanese town, further escalating hostilities between Israel and groups in Lebanon, despite a formal ceasefire.
The circumstances surrounding the deaths are not entirely clear and Israel has not commented on the Lebanese reports.
Attacks in Beirut
The Israeli military also carried out attacks outside Lebanon's capital, Beirut, according to the Lebanese state news agency NNA.
Another person was killed in an attack near the city of Nabatieh. According to the Lebanese Ministry of Health, the attack targeted a Syrian citizen and his 12-year-old daughter.
The two were traveling on a motorcycle when they were attacked by a drone.
According to the Lebanese Ministry of Health, "After the two managed to get away from the scene of the first attack, the drone attacked them a second time." The man was killed, but the girl survived - whereupon the drone attacked the girl "immediately and for a third time."
The girl's condition was said to be critical.
Highway attack
At the same time, Israel carried out further attacks on a highway connecting the capital with the southern parts of the country.
Lebanese Shiite militia Hezbollah said it responded to the raids by attacking northern Israel with a drone.
The attack took place in an area near Misgav Am, according to a Hezbollah statement. The target of the attack was a "gathering of Israeli soldiers."
The formal ceasefire between Israel and Hezbollah began on April 17.
