The deal came Thursday
night after a month of negotiations with representatives of the group,
said Hassan Tukur, principal secretary to President Goodluck Jonathan.
"We have agreed on the
release of the Chibok schoolgirls, and we expect to conclude on that at
our next meeting with the group's representative next week in Chad,"
Tukur said.
Officials provided few details about the release.
Doyin Okupe, a government
spokesman, did not specify when the girls would be freed. He said not
all would be let go at once, but a "significant number" would be
released soon.
"A batch of them will be
released shortly, and this will be followed by further actions from Boko
Haram," he said. "It is a process. ... It is not a question of hours
and days."
The Nigerian government consented to some demands by Boko Haram, but Okupe declined to provide details.
The government, he said, "is looking beyond the girls. We want to end the insurgency in this country."
"On the war front," he added, "we can say there is peace now."
The agreement was first reported by Agence France-Presse.
The terrorist group
abducted an estimated 276 girls in April from a boarding school in
Chibok in northeastern Nigeria. Dozens escaped, but more than 200 are
still missing.
Nigerian officials met with Boko Haram in Chad twice during talks mediated by Chadian President Idriss Deby, according to Tukur.
"The group has shown
willingness to abide by the agreement which it demonstrated with the
release of the Chinese and Cameroonian hostages few days ago," Tukur
said.
In cross-border attacks
by Boko Haram this week, eight Cameroonian soldiers and 107 group
members were killed in heavy fighting that lasted two days in northern
Cameroon, the country's defense ministry said Friday, according to state
broadcaster CRTV.
The militants led an
incursion near Limani, close to the border with Nigeria, on Wednesday,
equipped with heavy weapons, including at least one tank, CRTV said,
citing information from the defense ministry.
The fighting lasted two
hours and resumed on Thursday, when Cameroonian soldiers forced the
militants back across the border into Nigeria. Seven Cameroonian
soldiers were injured. A Boko Haram tank and other vehicles were
destroyed and weapons and ammunition were seized by Cameroonian forces,
according to CRTV.
A source involved in
talks with the militants told CNN last month that Nigerian government
officials and the International Committee of the Red Cross had
discussions with Boko Haram about swapping imprisoned members of the
group for the more than 200 schoolgirls. It is unclear, however, whether
the deal includes a prisoner swap.
