Libyan authorities have freed 28 Eritreans and seven Nigeria nationals who had been captured and enslaved for months by Islamic State (IS) militants.
The group, all but two of whom are women and children, escaped from Sirte, a former IS stronghold in central Libya, while forces from the nearby city of Misrata battled to oust the militants late last year.
Some of the women were said to be on their way to Europe when Islamic State fighters kidnapped and held them as sex slaves.
After they escaped from Sirte, they were investigated for possible ties to the group and held for several months in a Misrata prison.
However, on Wednesday, they were received by staff from the UN refugee agency and the Libyan Red Crescent, before being taken to a shelter for medical checks.
