Save the Children warns that food and medicine is running dangerously low at El Hall camp after Syrian government forces took control in January after clashes with Kurdish-led fighters.

The group's Syria director, Rasha Mahrez, says 60% of the roughly 20,000 detainees there are children detained with their mothers while their fathers were killed or imprisoned when ISIS fell seven years ago.

Thousands of the detainees are foreigners whose countries will not take them back.

Aid groups are calling for a humanitarian corridor to allow safe passage for aid.
