Speaking to newsmen in Abuja, the former Senate Leader said the figure did not include soldiers killed by Boko Haram and buried in other military cemeteries located in other parts of the North-East.
Ndume, the Chairman, Senate Committee on Army, denied reports of mass burial of soldiers killed by the terrorists.
He said the Senate panel was already investigating allegations that some non-governmental agencies were providing useful information to the Boko Haram leaders.
Naija News recalls that the Coalition for Good Governance and Change, a Civil Rights group had accused some international Non-Governmental Organisation, are passing classified military information to Boko Haram sect, thereby making the war against insurgency difficult.
The Civil Rights group, in its reaction to the allegation, charged the government to probe some of the international NGOs working in Borno State.
CGG claimed that the activities of some international NGOs in the northeastern part of the country are becoming very worrisome.
Princess Ajibola, the convener of CGG, accused the NGOs of helping terrorists out with their attacks against Nigerians, and help the terrorist group to recruit new fighters.
