The Nigerian Army has given more insight into the invasion of the Nigerian Defence Academy, Kaduna, on Tuesday.
Some gunmen described as bandits had stormed the place, killed two officers and abducted a major.
While many people continue to wonder how this could have been done, Director of Defence Information, Benjamin Sawyer, said investigation revealed that there was consistent rehearsal of the attack.
While some may link this to failure of intelligence, Sawyer said: “It was an unfortunate incident. We lost two of our very brave officers. Every security architecture is susceptible to breaches; it is unfortunate that that of the NDA was breached.
“I can tell you that these people had consistently studied and rehearsed what they wanted to do, because where they went to are the quarters for officers. The officers, who were killed, fought bravely against being abducted.”
