   The president of Nigeria, Muhammadu Buhari, has told the BBC that technically the security forces have won the war against the Islamist group Boko Haram. Mr Buhari, who came to power under a pledge to defeat the group this year, said the militants could no longer mount conventional attacks against government forces or centers of population. He said they had been reduced to suicide bombings and remained a force only in the heartland Born state.
   "They can not now marshal their forces and attack towns or attack military installations as they did before. I don't think this is mad talking and we have more substitute alongside the organized military. We have gotten some hardware fellow and support from Britain, America and France."
