At the sprawling al-Hol camp in northeast Syria, children pass their days roaming the dirt roads, playing with mock swords and black banners in imitation of Islamic State group militants. Few can read or write. For some, the only education is from mothers giving them IS propaganda.

It has been more than two years since the Islamic State group’s self-declared “caliphate” was brought down. And it has been more than two years that some 27,000 children have been left to languish in al-Hol camp, which houses families of IS members.

Most of them not yet teenagers, they are spending their childhood in a limbo of miserable conditions with no schools, no place to play or develop, and seemingly no international interest in resolving their situation.

Only one institution is left to mold them: remnants of the Islamic State group. IS operatives and sympathizers have networks within the camp, and the group has sleeper cells around eastern Syria that continue to wage a low-level insurgency, awaiting an opportunity for a revival.
