Iraq's National Security Service announced it had uncovered a corruption scheme involving fraud and embezzlement of payments intended for victims of Islamic State that saw more than 1 trillion Iraqi dinars ($760 million) taken from state coffers.
Iraqi state media said a three-month investigation had led to the arrest of more than 30 suspects including senior employees at several state entities such as retirement funds and the country's Martyrs Foundation.
The alleged corruption scheme based in Anbar province saw defendants falsify pension transactions with faked identities and false credit card information and sell confidential data.
The wasted funds totalled more than 1 trillion 32 billion Iraq dinars, state media said.
Islamic State rampaged across Iraq in 2014, at one point holding nearly a third of Iraq's territory before it was beaten back and declared territorially defeated in Iraq by the end of 2017.
