According to the Human Rights Watch, the servicemen of the 16th division trained by the US experts allegedly executed several dozen prisoners in Mosul's Old City. Two international observers also told the human rights watchdog about murder of four people by the division's soldiers and evidence pointing at more executions.
"The government of Iraq has investigated previous allegations and they have taken action, and we encourage them to present the facts of these investigations to the public," Dillon told reporters.
On July 9, Iraqi Prime Minister Haider Abadi officially announced that Iraqi security forces had finally liberated Mosul, the second largest Iraqi city, after months of fighting against Daesh.
Daesh terrorist group took over Mosul in June 2014. The operation aimed at liberating the city from terrorists began in October 2016. The eastern part of the city was rid of terrorists by Iraqi and US-led coalition forces in late January.
