The ceasefire agreement was reached on Friday but insurgency returned to the region just a day after.
The insurgents were said to have been killed on Sunday by security forces that repelled a planned attack on Damboa, south of Maiduguri, the Borno State capital.
Residents said “Boko Haram attacked the town again despite the ceasefire agreement but the attack was repelled by soldiers killing 30 of them”.
The residents also said “30 of the insurgents were killed during the attack” and commended the military troops for their gallantry and for not allowing the sect members to enter the town.
A security source, who requested not to be mentioned, told Channels Television that Boko Haram returned to Abadam, on Sunday, two days after killing eight people after the ceasefire agreement.
“The insurgents returned to the town again which currently has been deserted. Only the old people as well as the sick that are still in the town.
“They have taken over the town now and have comfortably camped outskirts of the town,” the source claimed.
The spokesman of the Borno Elders Forum, Bulama Mali Gubio, had informed Channels Television during an interview conducted on Sunday in Maiduguri that Abadam town was being attacked at the time of the interview and questioned the authenticity of the ceasefire agreement.
He said although the elders welcomed the ceasefire agreement and further negotiations, they were in doubt if the agreement was reached with genuine leaders of the sect.
