Abu Ahmad has sheltered at the frontier of the Israeli-occupied Golan Heights for days, fleeing an army offensive that has swept through southwestern Syria.

His family has already moved twice since the assault started in late June, and he worries the battles will creep toward them again. Now, they have nowhere left to go.

"We aren't even able to sleep more than a few hours, because of intense fear that the regime will attack us here," Abu Ahmad, 58, told Reuters.
