The Israeli Defence Forces (IDF) have reported on Twitter that a drone fell "adjacent to Israel's border with Lebanon, within Lebanese territory".
There is no more information about the incident yet.
In September, the Lebanese Army claimed Israeli drones dropped flammables on a Lebanese grove near the border with Israel in an anti-Hezbollah operation that triggered forest fires. In response, several anti-tank missiles were fired from Lebanon to target facilities in northern Israel.
The attack was followed by another one on Palestinian military positions in eastern Lebanon.
Lebanon has repeatedly objected to Israeli anti-Hezbollah operations in its airspace, insisting that they violate the country's sovereignty and UN Security Council Resolution 1701.
