Suspected Boko Haram Islamist militants have abducted more than 200 girls from north-eastern Nigeria from April 2014. The girls taken were aged between 12 and 15.
The latest kidnapping happened on 5 May 2014 in the village of Warabe, in Borno state. Boko Haram leader Abubakar Shekau released a video on 6 May 2014 confirming the abduction claim.
Recently, leader of Boko Haram had threatened to sell girls whom they had seized from their school.
Meanwhile, the US had offered assistance to Nigeria and the offer was accepted by it. US aid was a combination of military, law enforcement and other agencies who are going in, trying to identify where these girls might be.
Moreover, Nigerian police offered a 50 million naira reward on 6 May 2014 to anyone who can give credible information leading to the rescue of more than 200 schoolgirls abducted by Islamist rebels.
In April 2014, Boko Haram has attacked targets in the capital Abuja, with the deadliest attack so far coming on the same day the 200 girls were kidnapped in Chibok.
Also, Boko Haram which means Western education is forbidden has attacked numerous educational institutions in northern Nigeria.
