ABUJA, Nigeria >> Some frustrated Nigerians cast their ballots with flashlights while others stood watch at their polling stations as counting got underway late Saturday amid fears of vote tampering after a day of delays in Africa’s most populous nation.

Election officials blamed the delays on logistical issues, though other observers pointed to the upheaval created by a redesigned currency that has left many unable to obtain bank notes. The cash shortage affected transport not only for voters but also election workers and police officers providing security.

Voting ended well beyond schedule in many places after delays but some were still voting in a few areas where the exercise stretched into the night. In the northwest Bauchi state, Lagos-based Channels TV reported that voters still were voting using their flashlights at around 9 p.m.

In some states, voters stuck around to monitor the process and ensure results were not tampered with.
