The president of Nigeria, Muhammadu Buhari, has told the BBC that his military is close to defeating the Islamist group Boko Haram. Mr Buhari said the militants could no longer mount conventional attacks against government forces or centers of population and have been reduced to suicide bombings. Jessica M reports.

"President Buhari was confident. In a BBC interview, he said that we can now say that technically, we have won the war. He credited efforts to retrain and resupply the Nigeria army, saying that troops have almost expelled Boko Haram from Adamawa and Yobe state. The Jihadists, he said, are now strong only in their heartland of Borno State. He also said that many of the 1.5 million prople displaced by the fighting are now returning home. However, over the past two months, Boko Haram is reported to have mounted more than 100 attacks and killed more than 1,000 people."

He has now accused President Putin of again moving against him because of his support for opposition movements. He said he wanted to help the new generation to become future leaders.

"I think my task, my objective, as I see it, is to help young political activists in Russia to gain political experiences and to present themselves to society as alternatives to the existing regime."

Iraqi forces are continuing their offensive to try to drive the Islamic State fighters out of the center of Ramadi. Up to 300 Jihadist fighters are thought to be still in the town and they have shown no sign of giving up. Thomas Fessy reports from Baghdad.

"Ground forces have been concentrating on the city center, the last district held by Islamic State militants. And there, Iraqi troops and Sunni tribal fighters have faced sniper fire and have had to dodge roadside bombs and booby-traps planted by the Jihadists. Questions remain over the plight of thousands of people possibly trapped in the area. Yet security officials are confident Ramadi will be retaken this week." Thomas Fessy.

Christmas lights in American household used up more electricity during the holy season than some small centuries consumed in an entire year. According to researchers from the Center of Global Development, that's more power than is used annually by Ethiopia, Tanzania or El Salvador. Laura B has the story.

"The study says that America burnt 6.63 billion kilowatt hours over the Christmas season, shining brightly-colored lights and trees cross roof tops and gardens. That's enough power to run 14 million refrigerators. But it's still only a tiny fraction of what the US uses in a year. Compare that to El Salvador. Its annual electricity consumption is 5.35 billion kilowatt hours. The researchers say they are not anti-Christmas and the lights, they say, are a beautiful scene. But they do want to show the difference in energy use between rich and poorer countries."
