“They are envoys who answer to their leader Shekau who himself confirmed that these emissaries spoke on his behalf. That was confirmed in writing to the Chadian government,” he said, confirming local press reports that the negotiators were named Cheikh Goni Hassane and Cheikh Boukar Umarou.
Chad does not know where the abducted Chibok girls are being held, but Dago said it was likely they were outside of Chad and spread out over a wide area.
The Chinese hostages freed earlier under the agreement were found scattered across northern Cameroon, he said.
“They (Boko Haram) gave us guarantees that the girls are well but we don’t know physically where they are,” he said.
“But they have certainly dispersed them like the Chinese hostages, who were spread out over a large area.”
The two parties planned to meet again for a third time in Chad after the release of the schoolgirls to draft a roadmap to tackle more fundamental issues, Dago said.
“For the next stage of negotiations, the girls need to be freed. We cannot go into details as long as this question remains and it is a requirement of Chad that the girls are released before we start the next stage of talks,” he said.
