President Muhammadu Buhari has expressed deep sorrow over the killing of another aid worker as revealed in a video by Islamic State in West Africa Province (ISWAP).

A statement from the senior special assistant to the president on media and publicity, Shehu Garba, said the President condemned the gruesome murder of aid workers, who had made sacrifices and risked their lives to provide succor for traumatized people, urging humanitarian organizations not to be discouraged by the cowardly acts of terrorists.

It said President Buhari notes that the humanitarian spirit of aid workers had impacted greatly on the operations in the North East, appreciating them for all the sacrifices.

The President called for the release of all those taken hostage by bandits and terrorists across the country, and beyond.

President Buhari assures all humanitarian workers, especially those in the North East, and citizens held in captivity that his administration will intensely pursue and ensure their freedom by “using every possible means at the disposal of government”.
