The Washington Times newspaper said the report was drafted by the Saudi government but was never intended for public consumption.
The report speaks of an active flow of logistics, weapons, and training from Iran to armed Shiite groups, notably the Mahdi Army and the Badr organization.
The Badr Brigades, the armed wing of Supreme Council for the Islamic Revolution in Iraq, the largest party in the Iraqi government, is playing a crucial role in Iran's intelligence and military objectives in Iraq.
Additionally, Tehran gives financial support to social programs and Iraqi politicians sympathetic to Iran, the report said, and pointed the finger at the Americans for their failure to keep the peace and reconstruct the country.
On the Sunni resistance and insurgency in Iraq, the report cites Iraqi tribal leaders who say the resistance is being conducted by former military commanders of the ousted Baath party.
The report also advised the government to have contingency plans to deal with a possible civil war as the worst case scenario.
Meanwhile, there is no respite from the violence in Iraq.
A Pentagon quarterly report says that violence in the country is at an all-time high, with the worst toll being exacted on the civilian population because of the sectarian conflicts and death squads.Güncelleme Tarihi: 20 Eylül 2018, 18:16
