Group includes 11 US citizens, including five minors, but tens of thousands of people remained detained five years after defeat of IS
The United States has repatriated two dozen western citizens, half of them Americans, from Islamic State prison camps in north-eastern Syria where tens of thousands have languished.
The operation is the largest ever of US citizens and comes as rights groups warn of dire conditions in the camps still in use some five years after the ultra-violent extremist movement lost its last territory in Syria.
