For years, relatives of suspected ISIS fighters — including the families of many foreign fighters — have languished in massive detention camps in northern Syria. These camps, home to tens of thousands of children, have become the sites of a violent, festering humanitarian crisis, with no clear end in sight.

Now, that crisis may be about to get much worse. The camps are guarded by a U.S.-backed Kurdish military group, which is now being bombed by Turkey. They say if the Turkish offensive continues, they’ll have no choice but to abandon the camps to go fight. Experts fear this could have disastrous consequences — including a possible resurgence of ISIS.

Today, BBC investigative reporter Poonam Taneja, who is on the ground in northern Syria, joins us for a look at the camps and the disastrous situation that could unfold in the region.
