The Israeli military said a "drone on a routine mission in northern Israel fell", without elaborating on what it was doing or how it was downed. However, Israel says its drone "fell" in Lebanese territory.
Lebanon's Iran-backed Hezbollah downed an Israeli unmanned aircraft on Monday outside a southern Lebanese town after it crossed the border, the movement said in a statement.
The brief exchange of cross-border fire between Hezbollah and Israel marked the fiercest shelling exchange since the long-time enemies fought a deadly month-long war in 2006.
"The Britain-based Syrian Observatory for Human Rights said on September 9 that the overnight raids carried out by unidentified warplanes took place in the region of Al-Bukamal near the Iraqi border", reported Radio Farda, a USA government news outlet intended for the Iranian audience. It wants to stop Iran establishing a permanent military presence in Syria and has struck against advanced weapon shipments to Iran-backed Hezbollah.
The resolution banned all unauthorized weapons between the Litani River in south Lebanon and the United Nations -monitored frontier between Israel and Lebanon. The military said the drone went down Sunday, not Monday, and the reason for the discrepancy was not clear.More news: The women who have spoken out against Harvey Weinstein

Tensions rose in late August when two drones crashed in a Beirut southern suburb, which Hezbollah blamed on Israel and vowed to retaliate.
"I heard from the secretary-general of Lebanese Hezbollah that Hezbollah will give an appropriate and regrettable response to the slightest Israeli aggression on Lebanon".
Control of the area is split between US-backed Kurdish fighters and groups aligned with the Damascus regime, which is supported by Iran and Russian Federation.
Last week, when the Lebanese Resistance hit Israeli military vehicle in Avivim military base, Premier Benjamin Netanyahu claimed that no Israeli soldier was hit during the retaliatory strike. In a statement, it did not say what caused the crash and noted "there is no concern information could be taken from it".
According to Fox News, Iran is expected to move thousands of troops there once the facility is completed, as well as advanced weaponry such as precision-guided missiles.
