Chiefs of defense staff from Nigeria, Niger, Chad, Cameroon and Benin held talks in Abuja to determine strategies for a new, African Union-backed regional force against the terrorists, AFP reported.
The long-awaited Multi-National Joint Task Force, which was due to have been operational in November, has its headquarters in Chad's capital, N'Djamena, under a senior Nigerian officer.
In the meantime, troops from Nigeria, Chad, Niger and Cameroon have been fighting Boko Haram in northeast Nigeria for several months and have claimed a series of successes.
The Nigerian military announced on Monday evening that the chiefs of defense staff meeting was being held in preparation for talks between heads of state and government of all five countries.
Buhari, a former army general, has been Nigeria's president since May 29 and has made ending the six-year insurgency the top priority for his administration.
He immediately announced the transfer of the military command center from Abuja to the strategic city of Maiduguri, in the northeastern terrorist stronghold, and visited Niger and Chad to push for continued cooperation.
On Sunday, he travelled to the G7 summit of leading industrialized nations to garner further support from world powers on the security threat, including intelligence and training.
Buhari's nascent presidency has however seen an increase in suspected Boko Haram attacks, with 11 recorded since he took the oath of office and at least 93 deaths.
