The UN’s refugee agency (UNHCR) says it is unable to resettle the majority of migrants and refugees stuck at a transit centre in the Libyan capital, Tripoli.
There’s been growing frustration among the migrants as only a handful of them have been evacuated to Rwanda.
Rwanda had offered to take in 500 of the migrants, but that leaves thousands behind.
This week, the migrants have been holding protests, but the UNHCR says they have nowhere to take them.
The migrants, who are mainly from Eritrea, Ethiopia and Somalia, left their countries hoping to get to Europe, but are now stuck in war-torn Libya where they have faced torture.
There have been growing frustrations at the gathering and departure facility in Tripoli.
It is meant to be a transit centre where evacuees spend a day or two waiting to be moved.
But many have been there for over three months now.
Some came from a detention facility that was bombed in July. But some of their applications for evacuation have been rejected.
