Israel fired anti-aircraft missiles at an unmanned aerial vehicle that crossed into its airspace from Syria on Sunday afternoon, but failed to bring down the intruding aircraft.
The IDF said in a statement that neither of the two Patriot missiles launched managed to hit the drone, which returned to Syrian airspace.
The Israeli Air Force scrambled fighter jets in the Golan Heights following the launch, the Ynet news website reported.
The launches triggered air raid alarms across northern Israel. No rockets were known to have been fired into Israeli territory, however.
Israel has shot down drone and fighter aircraft that have flown near the border with Syria in the Golan Heights several times in recent years. The IDF downed a drone in August 2014 and a Syrian fighter aircraft in September of the same year.
