An Israeli drone crashed inside Lebanon on Saturday, coming down close to the demarcation line with the Tel Aviv, a military source.
"The drone crashed on the Lebanese border, inside Lebanese territory. Lebanese troops are in the area," the source told AFP.
There was no immediate comment from Israel, but the incident is not the first of its kind.
In February, an Israeli drone crashed on the Blue Line, the UN-demarcated line between Lebanon and Israel.
Israeli soldiers crossed into Lebanese territory during that incident to retrieve the wreckage.
Israeli aircraft regularly cross into Lebanese airspace, and the border area in southern Lebanon has been the scene of tense standoffs in the past.
The Blue Line was drawn up in 2000 by the UN after Israeli troops withdrew, ending a 22-year occupation of south Lebanon.
