More than 100 people, including Nigerians, have died in a shipwreck off the Libyan coast, Doctors Without Borders has claimed.
Survivors are being held in detention in the country, the humanitarian campaign group added.
The shipwreck occurred on September 1 and survivors include people with severe burns, pregnant women and babies. A team from the organisation provided medical care.
Doctors Without Borders said two rubber boats left the Libyan coast carrying migrants from Sudan, Mali, Nigeria, Cameroon, Ghana, Libya, Algeria and Egypt. One of the boats deflated and sank.
The Libyan Coast Guard recovered 276 survivors from both boats and brought them to the port city of Khoms. Only two bodies were reportedly recovered.
Libya has emerged as a major transit point to Europe for those fleeing poverty and civil war elsewhere in Africa.
