aThe position belonged to the Popular Front for the Liberation of Palestine-General Command and there were no injuries, Lebanese newspaper An-Nahar said.
The strikes came a day after two drones, which the Lebanese army and the Iran-backed Hezbollah group said were Israeli, crashed in the Hezbollah-dominated southern suburbs of Beirut.
One of the two drones was “booby-trapped” and exploded after hitting a Hezbollah media office, the group's spokesman, Mohammed Afif, said on Sunday morning.
The second landed and did not explode.
Hassan Nasrallah, leader of Lebanon’s Iran-backed militia Hezbollah, warned in Beirut on Sunday that “there won’t be any spot in Israel that will be safe” if Israeli planes entered Lebanese airspace again.
“I tell people who live in the north and everyone in occupied Palestine, they can’t live a single moment safely,” Mr Nasrallah said. “We won’t allow anyone to violate our sovereignty.”
He said any Israeli drones that flew over Lebanon would be shot down.
In the impassioned speech, Mr Nasrallah said the Israeli drone attack was the first since Hezbollah fought a month-long war with Israel in 2006. He described it as “very, very dangerous”.
Prime Minister Saad Hariri said the Israeli reconnaissance flights over Beirut were a clear breach of Lebanese sovereignty and the United Nations resolution that ended the 2006 war.
Mr Hariri said friends of Lebanon had a responsibility to protect UN Security Council Resolution 1701 “from the dangers of Israeli violations and their repercussions”.
An official from the Palestinian position in the Lebanese town of Qusaya told An-Nahar that three air strikes hit it on Monday, causing only material damage.
"MK planes (drones) targeted one of our sites with three small rockets. There were no casualties, only material damage," he said.
The Israeli army and Lebanese authorities are yet to comment.
