Lebanon's Hezbollah said it shot down an Israeli unmanned aircraft outside the southern town of Ramyah, the movement's Al-Manar TV said early on Monday.
The drone is now in the hands of Hezbollah's fighters, the Iran-backed group added in a statement, Al-Jazeera reports.
The group said it had "confronted" the drone with "appropriate weapons" as it was heading towards the southern Lebanese town.
In a statement, the Israeli military said one of its drones "fell inside southern Lebanon during routine operations". It did not say what caused the crash and added, "there is no concern information could be taken from it".
