Nigeria, Cameroon, Chad and Niger have agreed to quickly form a new force that would comprise 2,800 soldiers to fight against Boko Haram insurgents.
The defence ministers of Nigeria, Cameroon, Chad and Niger said they would contribute 700 troops each to the force.
According to the British Broadcasting Corporation (BBC), Niger’s Defence Minister, Karidio Mahamadou, said they were determined to “eradicate this curse”.
Boko Haram’s insurgency is focused on Nigeria, but has carried out some cross-border raids.
The bridge which serves as a key transport link between north-eastern Nigeria and Cameroon in Gamboru Gala was blown off by men of the deadly sect.
According to residents, cars and lorries loaded with goods were stranded on the highway.
The regional defence ministers met in Niger’s capital, Niamey, on Wednesday, to hold further discussions on the growing threat posed by Boko Haram.
While the meeting was ongoing, the Islamist group unleashed terror on Kaduna, killing 70 people.
A former Head of State, General Muhammadu Buhari (Rtd) who was caught in the violent attacks narrowly escaped death.
Efforts to step up regional co-operation gained momentum after Boko Haram caused an international outcry by abducting more than 200 girls from a boarding school in north-eastern Nigeria.
The girls are said to be held in the vast Sambisa forest, along Nigeria’s border with Cameroon.
