At least two civilians have been confirmed killed in the Monday attack.
Buratai is the country home of the immediate past Chief of Army Staff and current Nigerian Ambassador to the Republic of Benin, Tukur Buratai.
Sources said insurgents stormed the community on Monday evening, shooting heavy artillery and burnt down four cars.
The situation forced people to scamper for safety.
“Most residents have fled to Moringa, another town in Biu. The ISWAP came in large numbers shooting RPGs and anti-aircraft guns,” the security source said.
While reacting, the management of Army University Biu in a statement confirmed that two civilians lost their lives but that normalcy had since returned.
“The terrorists who came in, their numbers were met by superior firepower forcing them to retreat in disarray. Unfortunately, 2 civilian staff of the Institute paid the supreme price.
“Management wishes to commend troops for their gallantry during the attack and to commiserate with families of the fallen staff.
“Finally, management wishes to assure the general public that the Institute remains 100% operational as Security has been beefed up in the general area,” the statement said.
