Earlier on Wednesday, Israel fired a Patriot missile to intercept what initial findings showed was an unarmed drone that may have been on an intelligence mission, the Israeli army said.
Israeli Prime Minister Benjamin Netanyahu traveled to Russia Wednesday to meet with Kremlin President Vladimir Putin, for visit he called a "very important". A Syrian commander said the drone was engaged in local operations. "The IDF will not allow any violation of Israeli airspace and will act against any attempt to hurt its civilians".
The drone was an intelligence-gathering aircraft and belonged to the Syrian government and its remains have already been retrieved just south of the Sea of Galilee, nearly ten kilometers (six miles) inside Israel, an army spokesman told reporters.
"The UAV infiltrated the Israeli border from Syria, the IDF said".
Russian Federation was already working to distance Iranian forces from Syrian areas near the Israeli-occupied Golan Heights and had proposed that they be kept 80km away, but this fell short of Israel's demand for a full exit, the official said. "Obviously, our focus is on Syria and Iran".
Russian Defense Minister Sergei Shoigu said Moscow is ready to discuss the issue of supplying Syria with the S-300 missile system. Russian Federation has been a key ally of Syrian President Bashar Assad in the Syrian civil war and its forces on the ground have managed to turn the tide in Assad's favor in recent years.
He said the incursion threatened "the safety and security of Israel's northern cities and towns" and added that Israel has "repeatedly warned the Security Council of the destabilizing activities taking place in Syria and the threats they pose to Israel and the Middle East".
Responding to a reporter's question if Israel would establish some kind of relations with Syria, Lieberman responded: "Our assessment is that we are far from that, but we do not rule out anything".
