After the Nisour Square killings of 17 Iraqi civilians and the injury of 20 more by Blackwater convoy guards in a Baghdad traffic circle in September 2007, charges were brought against five guards. One pleaded guilty to a lesser offense in exchange for his testimony for the prosecution. Three were eventually convicted in October 2014 of 14 manslaughter charges and in April 2015 sentenced to thirty years plus one day in prison. These sentences were deemed unfair upon appeal and these three await resentencing. Another was convicted of murder and sentenced to life in prison; however, this verdict was overturned in August 2017.
