Police say the attacker targeted the local politician's car Monday in the city of Tal Afar. One of the politician's bodyguards also was killed.
In another development, Iraqi authorities say a court has sentenced a deputy minister of transport to eight years in prison for corruption.
Adnan al-Obeidi was arrested in September on suspicion of trying to extort half a million dollars from a foreign security company in return for granting it a contract.
Iraqi officials say the company informed anti-corruption officials about the extortion attempt and worked with authorities to catch al-Obeidi in the act of taking a bribe. Police later filmed him demanding $100,000 as a first installment of the bribe.
Some information for this report was provided by AP, AFP and Reuters.
