Borno State government said on Saturday the United Nations would resume humanitarian activities in the state and other parts of the North East.
Samantha Newport, Head of Communications, UN Office for the Coordination of Humanitarian Affairs, Nigeria, in a statement, quoted Kallon as saying this on Friday in Abuja.
Local media reported that large numbers of soldiers surrounded the United Nations building earlier Friday searching for arms.
"The UN does not have any information at this time regarding the reason or motivations for the unauthorised search". The operation was successfully conducted as over 30 houses were searched.
"It, therefore, became expedient to take preemptive action by combing the general area through a cordon and search operation".More news: Trump to order probe into China's intellectual property policy

Rumours have been swirling in Maiduguri that the leader of Boko Haram, Abubakar Shekau, has been hiding out in a compound with the same name. The clearance operations effort has been yielding several successes.
The UN Staff said the soldiers forced their way into the building.
The meeting arose following a late night cordon and search on the biggest premises of United Nations agencies in Maiduguri by soldiers as part of what the military later described as "a week long search operations for fleeing Boko Haram terrorists conducted on 30 houses in different areas, one of which included a property occupied by the United Nations around Pompamari".
"On the whole, the operation in the general area was successfully concluded but no arrest was made because the suspects were not found". Furthermore, the relationship between the Nigerian military and the United Nations has been cordial, aimed at working towards a more secured world in general and Nigeria in particular, which will be sustained.
In a statement emailed to journalists on Saturday morning, Shettima's spokesman, Isa Gusau, said given the critical intervention humanitarian workers have making in the affairs of internally displaced persons, Governor Kashim Shettima was anxious and had to place a phone call with the Deputy Secretary-General of the United Nations, Amina Mohammed.
