The United Nations Support Mission in Libya (UNSMIL) expressed concern over abduction of the head of the Libyan Red Crescent Society in Ajdabia city, some 900 km east of the capital Tripoli.
UNSMIL "is concerned for the safety and security of Mr Mansour Atti al-Maghrbi, Head of the Libyan Red Crescent Society in Ajdabia and a civil society activist," the mission said in a statement.
UNSMIL explained that al-Maghribi was abducted on Thursday when his car was intercepted by unknown armed men and his whereabouts remain unknown.
"The Mission calls for his unconditional release and urges all relevant military and security authorities to ensure a prompt, thorough and transparent investigation into this enforced disappearance," Xinhua cited the statement as saying.
UNSMIL stressed that all arrests and detentions should be based on due process guarantees and the rule of law.
