Israel said on Sunday that an Arab citizen had used a paraglide to fly illegally into neighboring Syria, where he planned to join Islamic State of Iraq and al-Sham (ISIS) insurgents in the four-year-old rebellion against Bashar Assad. The man's flight on Saturday across the fortified Golan Heights frontier jarred Israel, which has seen dozens of its minority Muslim Arabs or Palestinians from East Jerusalem reach the Syrian civil war through legal destinations. The Israeli military, whose aircraft dropped illumination flares around the Golan overnight before calling off the searches on Sunday, issued brief statements describing the paraglide as an Arab from the predominantly Muslim town of Jaljulia. He was not named. Israeli media gave his age as 23. Prime Minister Benjamin Netanyahu said the man's citizenship would be revoked as part of a wider policy against militants.
