Penetration prompts intensive search for fear the border-crosser may join IS

Israel said on Sunday that one of its citizens, probably a member of the Muslim Arab minority, had illegally flown to rebellion-wracked Syria by using a paraglider to cross the Golan Heights frontier.

Israeli media gave the man's age as 23 and quoted investigators as speculating that he sought to join Islamic State or other insurgents trying to bring down Syrian President Bashar al-Assad.
