BEIRUT, Sept. 1 (Xinhua) -- An Israeli drone threw Sunday incendiary bombs near the Lebanon-Israel border, causing massive fire in the area, according to a statement by the Labanese army.
The statement said that an Israeli drone violated Lebanon's airspace over Bastra Farm and threw incendiary bombs over woods of oaks.
"Investigations into this new development are currently ongoing in cooperation with the United Nations Interim Forces in Lebanon (UNIFIL)," the statement added.
Meanwhile, a Lebanese security source told Xinhua that four Israeli drones flew on Sunday morning over the Shebaa Farms and the villages adjacent to the farms.
The source added that one of the drones, labeled 'Inspire,' threw incendiary bombs over Bastra Farms, causing massive fire.
A big part of Shebaa Farms was destroyed on Saturday by heavy artillery fire and heavy machine-gun fire while the Israeli army was sweeping this area.
As a result, shell fragments were found at a UNIFIL's Indian battalion site at the western end of Bastra Farm.
Bastra Farm is the only farm in the Shebaa Farms which is a disputed region at the intersection of Lebanon, Syria, and Israel.
Tension has escalated between Lebanon and Israel in the past few days after an attack by two Israeli drones on Beirut's southern suburbs, causing heavy damage to the media center of Hezbollah in the area.
The attack prompted Hezbollah leader Sayyed Hassan Nasrallah to threaten a retaliation.
