Up to 117 migrants might have died when a rubber dinghy capsized in the Mediterranean off Libya, survivors said.
Flavio Di Giacomo, of the International Organisation for Migration, said three survivors were plucked to safety by an Italian navy helicopter on Friday, and they said 120 were aboard when the dinghy left Libya.
The navy said its plane launched life rafts after it spotted the sinking dinghy with about 20 people on board. It was not clear if some migrants had already fallen off.
The Italian Coast Guard said Libya asked a nearby cargo ship to search for survivors but no one was found.
The Italian news agency ANSA quoted Libyan authorities as saying a Libyan coastguard boat turned back after mechanical problems.
