The UN has called for the closure of all detention centres for refugees in Libya, saying the facilities are not fit to house migrants.
The appeal comes nearly two weeks after more than 50 people were killed in an air strike on a holding facility in the Libyan capital Tripoli.
The victims were mostly Africans attempting to reach Europe on boats after fleeing poverty and conflict.
The UN refugee agency has described the facilities in the centres “awful”. Thousands of migrants are being held in dire conditions in government-run detention centres across Libya.
The recent air strike on one of them during fighting in Tripoli has revealed how dangerous these facilities can be.
The UN refugee agency said the centres should be dismantled immediately, and their detainees freed into surrounding communities.
