Presidential elections scheduled for February 14 were delayed for six weeks as the military said the ongoing counter-offensive against Islamists Boko Haram meant that troops could not provide security on polling day. Elections will take place on March 28, with gubernatorial and state house assembly polls two weeks later. AFP PHOTO/PIUS UTOMI EKPEI
