He said: "The Defence Headquarters wishes to respond to AI report in which the group alleged that the Nigerian military and security forces were informed that a convoy of Boko Haram fighters were heading towards Dapchi in Yobe State to abduct some school girls, and failed to act accordingly".
The Nigerian army and the police received at least five calls up to four hours before militants raided a boarding school in Dapchi last month, but they did not take measures to stop the abduction or to rescue the girls after they were gathered into vehicles and driven away, Amnesty said in a news release.
Members of the militant Islamist group stormed the Government Girls Science and Technical College in Dapchi, Yobe state, on February 19, almost four years after a similar mass abduction in Chibok, Borno state.
Witnesses have told the Associated Press that armed fighters arrived in trucks in Dapchi, shouting: "Show us where the school is!"
"We have also noted that anytime the Boko Haram insurgents are dealt serious blows by our gallant forces, the AI is immediately out with one form of accusation or the other, against our armed forces".
The Peoples Democratic Party (PDP) on Tuesday said the recent report issued by Amnesty International (AI) has vindicated its stance that the President Muhammadu Buhari-led presidency and the All Progressives Congress (APC) must be held responsible for the abduction that took place in Dapchi.
Amnesty, whose researchers spoke to about 23 people and three security officials, said the army command in Geidam had told callers they were aware of the situation and were monitoring. "Is Amnesty International trying to undermine the outcome of this committee?", army head quarter quizzed.
When around 3 PM the insurgents arrived at Gumsa, where they stayed until 5 PM, residents of the town called their people in Dapchi informing them the insurgents were on their way to their town.
Villagers said the military did not arrive in Dapchi until shortly after the attack, Amnesty International said.
However, the military its reaction has dismissed the report describing it as "unfounded".
Amnesty equally alleged that a police source disclosed that officers fled the town over the fear that Boko Haram may "overpower them".
"Evidence available to Amnesty International suggests that there are insufficient troops deployed in the area, and that an absence of patrols and the failure to respond to warnings and engage with Boko Haram contributed to this tragedy", Amnesty's Ojigho said.
"There were security lapses which the military does not want to admit, but we shall speak the truth about what happened that day". Why has Amnesty International refused to communicate its findings with the committee set up by the federal government to investigate what happened before, during and after Dapchi girls abduction?
"The Nigerian authorities have failed in their duty to protect civilians, just as they did in Chibok four years ago", said Osai Ojigho, Amnesty's Nigeria director, in Tuesday's report.
