Human Rights Watch reported that violence linked to the April 2007 elections killed at least 300 people. Observers described ballot boxes seized by armed gangs, polling units that never opened, and results announced for areas where no voting had taken place.

EU observers said the elections fell far short of basic international standards. The winner, Umaru Musa Yar’Adua, later acknowledged that the process that brought him to office had been flawed and set up an electoral reform committee.
