Israel scrambled its air force after spotting a Syrian warplane approaching the Golan Heights.
A Syrian jet, believed to be a MiG-21, was tracked by Israeli radar Saturday as it flew toward the Golan and suddenly disappeared. Suspecting a possible covert attack, Israel dispatched two warplanes to the Golan, but they were recalled after no Syrian hostilities transpired.
Israeli sources said the MiG may have crash-landed within Syrian territory.
Israel has been on high alert for any Syrian retaliation for its alleged Sept. 6 sortie against a strategic military site in northern Syria.
