Details of Nigeria's peace deal with Boko Haram were revealed on Friday by the government of Chad which also sensationally disclosed that the sect's leader, Abubakar Shekau, wrote it confirming his emissaries to the recent peace meeting held in Chad.

Moussa Mahamat Dago, the number two official in Chad's foreign ministry confirmed all these to the media on Friday. The official stressed that Chad believed Nigeria's secret deal with Boko Haram Islamists to free more than 200 kidnapped Chibok schoolgirls would go ahead despite the breakdown of a truce and revealed that the key to the agreement was a prisoner swap.

The accord mediated by Chad for the release of the girls seized from Chibok in Borno State in April has been called into question since it was announced by the Nigerian military last week. A ceasefire supposed to be part of the agreement has been broken, and a further 25 girls were abducted this week.

Dago, according to Reuters, said it appeared some Boko Haram factions were refusing to abide by the deal, brokered by the Chadian foreign minister with two representatives of the Islamist group and two Nigerian negotiators at meetings in Chad on September 14 and 30.

"Quite possibly those who are fighting are dissidents that even they (Boko Haram) aren't able to control. So far, there is no reason for others to doubt this agreement," Dago told Reuters late on Thursday in the Chadian capital, N'Djamena.

"What I can say is that those that negotiated with the Nigerian government did so in good faith ... We are waiting for the next phase which is the release of the girls," he added.
