President Bola Tinubu on Saturday mourned the passing of Lieutenant General Chikadibia Obiakor (retd.), the first African to serve as the United Nations Military Adviser for Peacekeeping Operations, and the first to hold that role with the concurrent rank of Assistant Secretary-General of the United Nations.
In a statement signed by his Special Adviser on Information and Strategy, Bayo Onanuga, Tinubu described Obiakor as a shining example of Nigerian excellence whose contributions to global peace will endure for generations.
Obiakor died at an Abuja hospital on Wednesday, May 27, 2026, at the age of 75, having reportedly suffered a massive stroke days earlier.
Tinubu described Obiakor as an outstanding patriot who devoted his life to serving humanity, peace and national development.
“General Obiakor’s leadership in various peacekeeping missions and his commitment to conflict resolution and post-conflict reconstruction across several regions of the world helped strengthen the reputation of the Nigerian Armed Forces on the global stage.
“He was a shining example of Nigerian excellence. He served our nation with distinction and carried the banner of Africa with dignity in the international arena,” the President said.
Born on February 18, 1951, in Zaria, Kaduna State, Obiakor traced his roots to Awka South Local Government Area of Anambra State.
He attended the Nigerian Military School, Zaria, before joining the Nigerian Defence Academy in 1971 as a member of the 10th Regular Course.
He was commissioned into the Nigerian Army in 1973 and rose steadily through the ranks, serving in several strategic military and peacekeeping roles within and outside Nigeria.
On May 28, 2008, UN Secretary-General Ban Ki-moon appointed him Military Adviser for all United Nations peacekeeping operations worldwide, at a time when the UN’s peacekeeping numbers and responsibilities were at an all-time high.
He was tasked with advising on all military issues in the context of UN peacekeeping, which then deployed more than 110,000 personnel in conflict zones globally.
In that capacity, Obiakor became the first military adviser to the UN Department of Peacekeeping Operations to simultaneously hold the rank of Assistant Secretary-General of the United Nations.
He served in that position until September 2, 2010.
Prior to his appointment, Obiakor served as Force Commander of the United Nations Mission in Liberia following his appointment by then Secretary-General Kofi Annan.
He also served as Commander of the ECOMOG Artillery Brigade in Liberia between 1996 and 1997 and coordinated the Liberian elections under the regional peacekeeping mission.
Following his retirement from the Army in 2011, Obiakor continued to serve in various international assignments, including leading UN inquiry panels on conflicts and humanitarian incidents in South Sudan, Syria and the Democratic Republic of Congo.
He chaired the UN Board of Inquiry into the killing of Burundian refugees in Kamanyola in the DRC in 2018, and the UN Secretary-General’s Board of Inquiry into the destruction of humanitarian structures and facilities in North-West Syria from 2019 to 2020.
The United Nations on Friday mourned his passing through its spokesman, Stephane Dujarric, who at a news briefing in New York extended condolences to Obiakor’s family, friends, and the people and government of Nigeria.
Tinubu extended condolences to the Obiakor family, the government and people of Anambra State, the Armed Forces and the international peacekeeping community, praying that God grant his soul eternal rest.
