The United Nations has condemned the killing of one of the six workers held in captivity by the terrorist group, Boko Haram.

The insurgents had uploaded a video online showing how the humanitarian worker was beheaded, two months after six workers of Action Against Hunger, an international humanitarian organisation, were abducted.

AHMAD SALKIDA, a journalist well known for his link with the group, had equally through his verified Twitter handle, said the aid worker, a male was executed at a close range, saying he saw the video.

SALKIDA added that the Islamic State of West Africa Province (ISWAP), said it took the action because “the government deceived them,” following months of secret negotiations between a team of intermediaries and unnamed officials.

The execution of the worker, is coming against the backdrop of allegation by the military that AAH was conducting illicit affairs supporting the terrorist group.

The United Nations Humanitarian Coordinator in Nigeria, EDWARD KALLON described the incident as appaling and saddening.

President MUHAMMADU BUHARI has joined his Zambian and Ethiopian counterparts in calling for unity among African countries to demand unconditional repatriation of assets stolen from the continent.

The call came at a high-level event on Illicit Financial Flows held on the sidelines of the ongoing 74th United Nations General Assembly in New York.

The theme of the event was “Promotion of International Cooperation to Combat Illicit Financial Flows (IFFs) and Strengthen Good Practices on Assets Recovery and Return to Foster Sustainable Development”.

According to some estimates, illicit financial flows from Africa is as much as 50 billion dollars annually.

In his address, BUHARI stated that Nigeria alone lost about 157.5 billion dollars to IFFs between 2003 and 2012.

He said although his administration had recovered “millions of dollars stolen from our country” in the last five years, a lot more was still stuck in foreign bank accounts.

According to him, a combination of “international laws, different jurisdictions and justice systems”, make it deliberately difficult for repatriation noting that any lasting solution to the challenges would require international cooperation and coordination.
