Kano - Nigeria's government may have negotiated a supposed ceasefire with only one faction of Boko Haram, an influential regional group has said, as violence continued unabated in the far northeast.
The Borno Elders Forum, made up of retired senior civilian and military officials from the state, said attacks in recent days indicated that not all Boko Haram fighters were aware of the deal.
"If they are aware and they are in agreement that there is a ceasefire, I don't think they would continue attacking innocent people and taking over places," said spokesman Bulama Mali Gubio.
"It is either (that) those the federal government is negotiating with are not the Boko Haram but the usual 419ers or it is just some kind of mockery," he told reporters in Maiduguri on Sunday evening.

The term 419 refers to the section of the Nigerian penal code that deals with fraud and which has become a catch-all for con artists.
Gubio was speaking after senior military and intelligence officials in the violence-wracked region told AFP at the weekend that they had not been informed of the ceasefire.
There was a wave of attacks in Borno and Adamawa, including one on Sunday evening in Damboa, southwest of Maiduguri, where soldiers fought the militants.
The Borno Elders Forum, which last month warned that Boko Haram had surrounded Maiduguri and were preparing to take over, suggested Abuja had not negotiated with the entire group.
"If the federal government does not know who the real Boko Haram are, I think they should come here to find out from us," Gubio said.
"The real Boko Haram who are killing us, who are burning our towns and villages, are not the Boko Haram that a peace deal was reached with."
The government claimed a deal was reached after talks in Chad, which included provisions for the release of more than 200 schoolgirls kidnapped from the Borno town of Chibok in April.
But no detail of the terms and conditions for Boko Haram to lay down their arms was given and many observers expressed doubts about the identity of the group's supposed envoy.
Gubio said the deal was "very sketchy" and questioned whether it meant that each side would retain its positions, which for Boko Haram would mean the towns it has captured in recent months.
