On Friday, the Israeli aircraft entered the southern border town of Naqoura, the Lebanese Army said in a statement.
The statement added that the aircraft flew over several areas before heading out.
Several similar overflights have been reported since Wednesday, when 10 Israeli planes were spotted violating the country’s airspace.
Israel carries out such flights on an almost daily basis, claiming they are surveillance missions.
These flights are in breach of the United Nations Security Council Resolution 1701, which obliges Israel to keep out of Lebanon following its 2006 war on the country, which left some 1,200 Lebanese dead.
