Foreign fighters flow to Syria
An estimated 15,000 militants from at least 80 nations are believed to have entered Syria to help overthrow the regime of President Bashar al-Assad according the CIA and studies by ISCR and The Soufan Group.

Western officals are concerned about what these individuals may do upon returning to their native countries. Related story.
