Freedom fighters turning to Al Qaeda-linked groups

Istanbul (CNN) -- A year ago, Ibrahim Qobani was an idealistic 19-year-old revolutionary who sang about freedom.

Always dressed in a scarf and fingerless gloves woven with the colors of the Syrian rebel flag, Qobani worked with a team of pro-democracy activists in Syria's northern Idlib province. He would sing from the rooftops during boisterous anti-government protests, complete with humorous animations that begged the international community to help stop Syrian government atrocities.
