Nigeria’s president and leading opposition candidate have appealed for calm after the shock move to delay elections for a week.
President Muhammadu Buhari said he was “deeply disappointed” but urged people to refrain from “civil disorder”.
Main rival Atiku Abubakar called for patience but accused the administration of “anti-democratic acts”.
Election officials cited “logistical” reasons for the 11th-hour delay in presidential and parliamentary polls.
