As Syria’s war enters its fifth year, its refugees are fading deeper into the background. At a conference in Kuwait last week, countries promised more aid, but donor fatigue has left humanitarian organizations unable to help people like Deen, and that’s creating an opportunity for the Islamist militants who play a growing role in the conflict. This month, Islamic State and and al-Nusra Front militants took over much of the Yarmouk Palestinian refugee camp in Damascus.

Photographs purportedly showing more than 40 UN peacekeepers seized by Islamist militants on Syria’s side of the Golan Heights – along with their identity cards – have been posted on social media.  The al-Qaeda linked Nusra Front says the captives, all from Fiji, were detained on Thursday because their UN mission was helping Syria’s government and had ignored the suffering of its people. It says they are being treated well.

The five-day ultimatum by the leader of Jabaht al-Nusra (al-Nusra front) - Abu Mohammed al-Golani - to the leadership of the  Islamic State of Iraq and the Levant (ISIL), and other Islamist factions, to end fighting or be "expelled" from the region is the latest in the troubled affair between the two al-Qaida affiliates in Syria. 

Al Qaeda is building its most dangerous stronghold ever in the borderlands between Syria and Iraq. Hundreds of new jihadist fighters are flocking to this battlefield in the heartland of the Middle East. And with the civil wars in both countries all but certain to endure for the foreseeable future, the danger from this stronghold is growing.
