Abuja - The governor of the most hit Nigerian state by the Islamist insurgency said in a statement that Nigerians, who are displaced by militants of Boko Haram terrorist group, will not return to their homes by the end of May as originally planned. Recurrent attacks by the militants, who have ties to the Islamic State militant group (ISIS), and ongoing operations by the Nigerian military means that the Borno State government will miss its deadline for closing camps for all internally displaced people (IDP) in the state, according to Kashim Shettima, the State Governor. Shettima has said that returning Internally Displaced Persons (IDPs) to the Bama Local Government Area before Ramadan is no longer feasible because of current military operations in Sambisa Forest. Boko Haram took up arms against the Nigerian government in 2009 and has killed thousands and displaced more than two million people across Nigeria, Niger, Chad and Cameroon. The group launched their insurgency in Maiduguri, the capital of Borno State, and Borno has been the worst-affected by the violence.
