Aid agencies raise alarm as solo children cross Chad border to flee Sudan fighting

Unicef says ‘more and more unaccompanied children’ among thousands of refugees streaming across 1,000km-long border

Hundreds of unaccompanied children have crossed the border from Sudan into Chad in recent weeks as fighting separates families and forces minors to make the arduous journey to safety without their parents.

Humanitarian workers say “more and more” children are arriving alone in the neighbouring country, to which more than 100,000 refugees, about 60% of them under-18s, have fled since fighting erupted between rival military factions in mid-April.
