The leader of Nigeria's Islamic extremist group Boko Haram has denied agreeing to any ceasefire with the government and said more than 200 kidnapped schoolgirls all have converted to Islam and been married off.
In a new video released late Friday night, Abubakar Shekau dashed hopes for a prisoner exchange to get the girls released.
"The issue of the girls is long forgotten because I have long ago married them off," he said, laughing. "In this war, there is no going back."

Nigeria's chief of defence staff, Air Chief Marshal Alex Badeh, on October 17 announced that Boko Haram had agreed to an immediate cease-fire to end a five-year-old insurgency that has killed thousands of people and driven hundreds of thousands from their homes in northeast Nigeria.
But attacks and abductions have continued with the extremists this week seizing Mubi, a town of more than 200,000 people. Fighting also continued Friday in Vimtin, the nearby village where Badeh was born.
Shekau in August announced that Boko Haram wanted to establish an Islamic caliphate, along the lines of the IS group in Syria and Iraq. Fleeing residents have reported that hundreds of people are being detained for infractions of the extremists' version of strict Sharia law in several towns and villages under their control.
Boko Haram's kidnapping of 276 schoolgirls taking exams at a boarding school in the remote northeastern town of Chibok in April prompted an international campaign for their release and criticism of Nigeria's government for not acting quickly to free them. Dozens of the girls escaped on their own in the first couple of days, but 219 remain missing.
Unconfirmed reports have indicated that the girls have been broken up into several groups and that some may have been carried across borders into Cameroon and Chad.
The government had said it had negotiated with two Boko Haram leaders in Chad, with talks hosted by President Idriss Deby, and that it was confident the girls would be freed soon.
Shekau's announcement further discredits the government of President Goodluck Jonathan, who on Thursday formally announced his candidacy for elections on February 14, 2015 in Africa's most populous nation. Nigeria, with some 160 million people, is divided almost equally between Muslims who dominate the north and Christians in the south. The West African nation is the biggest oil producer on the continent and has its biggest economy.
Jonathan's failure to curtail the insurgency and many corruption scandals are not expected to dim his chances of success. The election, though, is expected to be the most hotly contested since his People's Democratic Party took power after decades of military dictatorship ended in 1994.
Dozens of ruling party legislators have defected to the coalition All Progressives Congress, losing the PDP its majority in the lower house of Parliament. But the coalition is weakened by its inability to choose a presidential candidate, and primaries in December will be contested by three powerful northerners who all are Muslim.
Jonathan, a Christian from a minority southern tribe, has been criticised for ignoring an unwritten party rule to alternate power between Christian and Muslim leaders, adding a religious and ethnic dimension to the election.
