At least 34 officials from Iraq’s interior ministry have been arrested, possibly in connection with corruption and working to rebuild an illegal party formed by supporters of Saddam Hussein’s Ba’ath party, according to ministry officials.

Those arrested include both Sunni and Shia and high-ranking generals at the interior ministry, which oversees the country’s police and other security services. Most of those arrested were members of the traffic police, including the general who leads the department, said officials who spoke on the condition of anonymity because of the sensitivity of the matter.
