Islamist militants in Nigeria have freed 10 people kidnapped five months ago, local media reports.
One includes an aid worker from the UN refugee agency.
They are believed to have been held by the Islamic State West Africa Province (Iswap) – a Boko Haram offshoot which has previously killed hostages after failed negations.
A UNHCR spokesman told the BBC that their employee was freed on Monday and commended the Nigerian authorities for their help.
The victims are said to be undergoing medical checks and security debriefings in Maiduguri, the capital of north-eastern Borno state, before they are allowed to join their families.
