The Nigeria Governors Forum (NGF) approved the withdrawal of $1 billion from the Excess Crude Account by the Federal Government to intensify the war against Boko Haram after a National Economic Council (NEC) meeting on December 14.
While speaking to State House correspondents after the meeting, Edo State governor, Godwin Obaseki, said the approval was announced by Zamfara State governor, Abdulaziz Yari, who's the chairman of the NGF.
He said, "Pleased with the achievements that have been made till date in the fight against insurgency, particularly in the North East, the governors of Nigeria through their chairman announced at the NEC meeting that the governors have given permission to the Federal Government to spend the sum of $1bn on the fight of insurgency.
"This money is supposed to be taken from the Excess Crude Account.
"As you know, the issue of security, particularly with regard to the North East, is a very comprehensive response by federal forces.
"So, we expect that the contribution of the states to these efforts will cover the whole array of activities required to secure the country and counter insurgency.
"We expect that the amount will include but not limited to purchase of equipment, procuring intelligence and logistics and all what is required to ensure that we finally put an end to the scourge of insurgence."
Since the insurgency of the terrorist group escalated after a 2009 crackdown by the military, Boko Haram, chiefly under the leadership of Abubakar Shekau, has been responsible for the death of over 20,000 people and the displacement of more than 2.5 million scattered across Internally Displaced Person (IDP) camps across the country and its neighbours.
After a massive military operation resulted in the displacement of the group from its primary base in the infamous Sambisa Forest, it has resorted to suicide bomb attacks on soft targets and carried out daring attacks on military bases, with hundreds of captives still unaccounted for.
