An official inquiry has found that more than 500 people were killed in violence related to Tanzania's elections, according to a newly released report.

The inquiry's findings document the scale of deadly incidents that occurred during the electoral period, though the official report does not identify who was responsible for the deaths.

Opposition parties have previously accused security forces of involvement in the violence. However, the official investigation has not attributed blame to any specific groups or individuals for the fatalities.

The death toll represents a significant number of casualties connected to the electoral process in the East African nation. The inquiry's findings provide an official accounting of the violence that accompanied the elections.

The report's release comes as questions remain about accountability for the deaths and the circumstances that led to the widespread violence during what should have been a democratic process.
