Qassem Al-Araji made the remark during a trip to the eastern governorate after announcement was made about a major victory against Daesh.
He said the chain of victories against Daesh that has begun in Diyala will not cease.
Al-Araji also held meetings with security and intelligence officials of the province.
Talib al-Mousavi, the commander of Iraq’s Popular Mobilization Units (PMU, also known as Hashd al-Sha’abi), on Saturday announced the dismantling of the largest Daesh network in Diyala.
He said Daesh had planned to carry out terrorist operations against civilians in Diyala but failed with a pre-emptive operation implemented by the PMU and security and army forces.
