"At circa 0500 hours today, members of the Nigerian security forces entered the United Nations base for humanitarian workers in Maiduguri without authorization".
The Nigerian Army acted on intelligence reports in combing some areas of Maiduguri Metropolis which included a house purported to accommodate some staff of an worldwide humanitarian organisation.
"The United Nations is extremely concerned that these actions could be detrimental to the delivery of lifesaving aid to the millions of vulnerable people in the northeast of Nigeria".
Speaking to reporters separately, the Theatre Commander of Operation Lafiya Dole, Major Gen. Ibrahim Attahiru described the United Nations as one of its strongest and worthy allies in the counter insurgency fight against Boko Haram.
The United Nations' relationship with Nigeria is intact, a U.N. official said on Saturday, despite a military raid on a compound belonging to the worldwide body in the conflict-ridden northeast.
While the United Nations now does not have any information related to the unauthorized search, the statement added, Mr. Kallon will seek an explanation for its motivation.
Shettima also put a call through to UN's Deputy Secretary-General, Amina Mohammed, to reassure the organisation of government's commitment to safeguarding the lives of the humanitarian workers and ensuring respect for worldwide protocol. The statement, signed by Lieutenant-Colonel Kingsley Samuel, said the searched facility was without designation.
"It has forced the Boko Haram Terrorists (BHTs) to change tactics and resort to employment of suicide bombers to target military locations and the populace". On August 10, 2017, Theatre Command received information from one of its credible sources that some high value BHT suspects had infiltrated into Pompomari Bye Pass.
In the last one week cordon and search operations were conducted in Jiddari -Polo, Muna Garage, Jakana amongst several other areas. About 30 houses were searched during the exercise and no arrests were made.
General Ibrahim Attahiru, who commands operations in Borno state where Maiduguri is located, said on Saturday that the army "will continue to work toward providing and enabling a conductive environment to United Nations agencies to enhance their operations".
"The general public is cautioned to avoid peddling rumours which may cause disaffection and to remain law abiding".
"We will continue to collaborate with the United Nations humanitarian agencies to achieve the goals of the counter-insurgency campaign and other developments to address the humanitarian crisis in the northeast region", he said.
