Efforts are under way to secure the release of six crew members of a UN food agency’s helicopter who disappeared in Sudan.

The UN World Food Programme (WFP) says the helicopter was flying from South Sudan to Khartoum, the capital of Sudan, for regular maintenance on Monday when it made an emergency landing in the Sudanese region of South Kordofan.

According to media reports, the crew members are being held by rebels of the Sudan People's Liberation Movement - North, which has been fighting the Khartoum government since 2011.

To find out more about this incident, Sworo Charles Elisha spoke to George Fominyen WFP’S communication’s officer for South Sudan.
