In Nigeria Boko Haram militants are advancing to different towns in a similar way that Islamic State fighters are in the Middle East.
Thousands of Christians have been killed in Nigeria with more than 200 schools girls still missing after they were kidnapped by Boko Haram.
Stuart Windsor from Christian Solidarity Worldwide told Premier there needs to be more focus on the problems in Nigeria.
"Thousands of Christians are being killed.
"Christians are being beheaded, Christians are being murdered, Christians ladies are being married off to terrorists and being taken and abducted and the media is just not saying much about it," he said.
According to the AFP news agency a spokesman for the Roman Catholic Diocese of Maiduguri claimed militant fighters had carried out atrocities against Christians in the town of Madagali.
Last week details emerged of the beheading of a six year old Christian boy by the extremists.
Charity The Voice of Martyrs heard from witnesses about the 'well-planned' assault on Attagara at the start of June.
More than 100 militants entered the village just as Sunday church services started, opened fire and started attacking people with machetes.
It's claimed the boy was thrown into a ditch before being beheaded as others tried to save him.
It's thought Boko Haram has killed more than 5,000 civilians between July 2009 and June 2014, including at least 2,000 in the first half of 2014.
CSW's Stuart Windsor added: "From the evidence we have they are conducting religious and ethnic cleansing in many Christian areas."
