Iraqi officials say at least 40 people are dead in three bombings in
northern Iraq and the capital, Baghdad, about one week after U.S.
combat troops formally withdrew from Iraqi cities.
Officials say two suicide bombers killed at least 34 people and wounded 62 others in the northern town of Tal Afar Thursday.
Police said the first bomber detonated an explosives vest in the town about 400 kilometers northwest of Baghdad. The second attacker blew himself up minutes later, as people gathered to help victims of the first blast.
Elsewhere, police in Baghdad say a bombing in Sadr City killed at least six people and wounded 16 others early Thursday.
And authorities say a roadside bombing appeared to target the convoy of Iraq's central bank governor in Baghdad's Karrada district. He was unhurt in the blast.
Iraq has seen multiple deadly attacks since the change in security on June 30.
A member of parliament, Hanin Qudwa, told journalists that he thinks those responsible for the recent violence are trying to affect the political process.
On Wednesday, police said a series of attacks in and around the northern city of Mosul killed at least 14 people.
Authorities say car bombs exploded within minutes of each other near a Shi'ite mosque in Mosul and in a district on the outskirts of the city. Some 30 people were wounded in those attacks.
