The United Nations Secretary-General, Antonio Guterres, has said perpetrators of terrorism in Nigeria must be held accountable.
Guterres, who was in the country on a two-day visit, called for the prosecution of the attackers on the UN House in Abuja on August 26, 2011.
He assured that the UN remains steadfast in its commitment to support a peaceful Nigeria for all people.
The UN Chief thanked the government of Nigeria for its support in repairing the UN House which has enabled staff to return.
Recall that the attack claimed the lives of 23 UN staff and civilians and injured 16 others.
