Islamic State militants have accepted a pledge of allegiance by the Nigerian-grown Boko Haram extremist group, a spokesman for the Islamic State movement said on Thursday.
On March 7, Boko Haram's leader, Abubakar Shekau, posted a video recording online that it pledged allegiance to IS.
Yesterday the head of the information policy of IS, Abu Mohammed al-Adnani, said that Boko Haram's pledge of allegiance has been accepted, claiming the caliphate has now expanded to West Africa, Interfax writes.
