The Israeli air force shot down a drone after it crossed into southern Israel on Saturday, the military said, but it remained unclear where the aircraft had come from.
It flew over Israel for less than 30 minutes and did not carry any explosives on it. The while Israeli cyber experts tried to identify its satellite controller.
A military spokesman said two F-16 fighters were flew from a southern air base at around 10 a.m. local time (0800 GMT) after a ground control station identified the drone, which was shot down over the Yatir Forest, an area in the northern Negev.
Army troops are currently searching the Negev desert on Saturday near where the military had shot it down in an effort to locate debris that could shed light on its origin and objective, while the Air Force launched its own investigation into the incident, said Capt. Roni Kaplan..
Now the big question is where the drone came from.
According to Palestinian Ma'an news agency,the drone was departed from the Gaza Strip and managed to fly over several Israeli towns and bases in southern Israel, including the city of Beersheba.
On a twitter Israeli parliament member Miri Regev, a former chief spokesman of the military,wrote "Iranian drone launched by Hezbollah".
But defence authorities did not confirm its link with Hezbollah.In other words they are indicating the strong involvement of Iran behind this attempt.
Defence ministerin a statement said,"We view with great severity the attempt to compromise Israeli air space and will consider our response in due course."
