The United Nations’ humanitarian coordinator for Nigeria, Edward Kallon, has expressed grave concern over the unauthorized search of a UN base for humanitarian workers by security forces in Maiduguri, Borno State.

Security forces entered the humanitarian base at 5am on Friday without authorisation and seared the tented camp for close to three hours, the coordinator lamented in a statement.

The UN insists it still doesn’t have any information regarding the “reason or motivations” for the unauthorised search, but is working with government to resolve the issue.

“The humanitarian crisis in Nigeria’s north-east is one of the most severe in the world today,” said Kallon.

“I am extremely concerned that these actions could be detrimental to the critical work that is being carried out every day to support the most vulnerable in the region and I call upon the Government of Nigeria to provide clarification.”
