According to Nigerian government officials, in addition to the ceasefire, the nearly 300 schoolgirls — who were kidnapped as they took exams in Chibok — will be released, reports the BBC.
Nigerian presidential aide Hassan Tukur told BBC Focus on Africa that the agreement was sealed after a month of negotiations, mediated by Chad.
As part of the talks, a government delegation twice met representatives of the Islamist group.
Mr Tukur said Boko Haram had announced a unilateral ceasefire on Thursday and the government had responded.
“They’ve assured us they have the girls and they will release them,” he said.
“I am cautiously optimistic.”
While the Nigerian government hasn’t revealed what concessions they have made to secure the girls, they have said that they will be having a meeting next week to hash out the particulars of the release.
