Abuja — Hundreds of Nigerian civil societies say discrepancies in election tallies suggest the turnout was inflated in defeated President Goodluck Jonathan's southern strongholds.
The groups say the differences do not invalidate the victory of former military dictator Muhammadu Buhari, but should be investigated before April elections for state governors.
The Transition Monitoring Group's count shows 40.6 percent of voters turned out in Nigeria's south-south zone compared to an official 55.9 percent.

The region includes populous, oil-rich Rivers state, which remains under curfew after opposition protests and the bombing of an electoral commission office following Saturday's bitterly contested election.
The group of more than 400 civic groups says its count from thousands of monitors has Buhari winning 59.4 percent of votes to Jonathan's 39.2 percent. Official results have 53.9 to 45 percent.
