A shot from a propaganda movie made by foreign jihadists near the northern Syrian town of Atmeh, a transit station for jihadists who usually arrive at the nearby Turkish airport in Hatay. As thousands of foreign jihadists enter the country, there are growing tensions between more secular and more extreme rebel elements.
Some remain in the region, while others continue on to Aleppo, to the mountains of Latakia, to Rakka in the east, or to wherever the unclear front happens to be. Here, another frame from the same propaganda video.
Some Syrian rebels team up with the jihadists, but many find the foreigners sinister. And even when the latter do fight against regime troops, Free Syrian Army (FSA) commanders are puzzled as to why commanders like Abu Omar al-Shishani, from Chechnya, aren't using the ammunition and anti-aircraft missiles they have obtained. Indeed, the FSA commanders fear the jihadists could use their weapons against Syrian rebels or even in terrorist attacks elsewhere in the world.
Many rebels and citizens would like to see the more extreme Islamists leave the country -- especially the more brutal ones. The most radical emir in the north has been Abu al-Banat, a former Russian officer from the Caucasus republic of Dagestan who converted to Islam and has gathered disciple-like supporters since then (seen here). However, his public beheading of three men in April prompted supporters to abandon him and rival rebel groups to capture him.
