Meanwhile, Turkish warplanes bombed three villages in northern Iraq, where Kurdish militants were thought to be located, a border security officer said.
In Baghdad, three members of an Awakening Council working at checkpoints in a Sunni neighborhood were shot and killed Wednesday by attackers, CNN reported. The Awakening Council is one of the anti-al-Qaida Sunni groups backed by the United States.
Also Wednesday an Interior Ministry official said Abdul Rahman Dawood, a senior member of Prime Minister Nouri al-Maliki's Dawn party, was wounded when his home was bombed.
In the attacks in northern Iraq, the border security official told CNN no one was reported injured from a bombing raid that lasted for about an hour.
The official said the latest strikes by the Turkish military against Kurdistan Workers' Party militants occurred in the Duhuk province in Iraq's Kurdish region.
