Authorities say clashes have broken out between rival ethnic groups of refugees and other migrants at a detention camp on the eastern Aegean Sea island of Lesvos.
The trouble at the Moria hot spot started shortly after midnight in a wing of the camp where minors are held and then spread, authorities said, adding that child refugees from Syria had been assaulted by a group of Afghan children.
An unspecified number of children were injured while about 40 of them escaped into nearby fields. Order was restored around 4 a.m. after intervention by riot police. Authorities were trying to locate the missing children.
Nearly 5,000 migrants and refugees are currently sheltered on the islands of Lesvos. Local authorities are demanding immediate government action to decongest overcrowded migrant facilities.
