Religious violence in Nigeria refers to Christian-Muslim strife in modern Nigeria, which can be traced back to 1953. Today, religious violence in Nigeria is dominated by the Boko Haram insurgency, which aims to impose Sharia on the entire nation. Christians have suffered hugely, making up the majority of the more than two million people who have been forced from their homes by militant Islamist group Boko Haram. The most publicised atrocity was the kidnap of 276 girls from Chibok School in 2014 but that is just one of many terrible outrages. More than 2,000 women and children have escaped or been recovered from Boko Haram and many more are almost certainly still in captivity. Those who have escaped say women and girls are forced into marriage. Those who refuse are either killed or forced into slavery. Christian men have also been killed. In one area, the attackers reportedly used chainsaws to save bullets. The Humanitarian Aid Relief Trust (HART) says the nomadic Fulani group has targeted Christian farmers with an 'aggressive and strategic land grabbing policy' under the slogan: 'Your land or your blood'. Boko Haram has attacked both Muslims and Christians, increasingly raiding Fulani herding villages to steal livestock. The violence has spread to neighbouring Niger, Chad and Cameroon, prompting a regional military coalition to fight the militants. On top of that, another group called ISWAP which split from Boko Haram has launched a series of attacks on civilians in recent months. ISWAP fighters have mounted fake checkpoints and killed and abducted civilians in an ongoing conflict in the north-east of the country. Credit: BBC
