Over a hundred migrants drowned in a shipwreck off the Libyan coastline earlier this Month.
Aid agency, Medecins Sans Frontieres (MSF) in a statement, said two rubber boats set off on September 1, but one of the vessels deflated and sank.
About 276 survivors were eventually taken to the Libyan port city of Khoms, around 100 km (62 miles) to the south-east of the capital Tripoli.
MSF says the group is now being held in “arbitrary detention”.
