Iraq's human rights minister Mohammed al-Bayati said the remains of 597 victims of the Speicher massacre had been dug up.
In June 2014, armed terrorists captured hundreds of young, mostly Shiite recruits from Speicher military base, near the northern city of Tikrit.
They were then lined up in several locations and executed. It is believed up to 1,700 soldiers were murdered in cold blood.
Some were pushed into the Tigris river and others hastily buried in locations discovered when government and allied forces retook Tikrit from ISIS in April this year.
'The remains of 597 Speicher martyrs have been exhumed,' al-Bayati told journalists in Baghdad yesterday.
In April, Iraqi forensic teams began the gruesome task of uncovering the bodies of the young army recruits on the banks of the Tigris River.
