A taxi driver detonated a car bomb Saturday near a check point in northern Iraq, killing four people, including an Australian cameraman, reports said.
The suicide bombing occurred at the Khormal checkpoint near the Northern Iraqi city of Halabja, the reports said.
The taxi driver, a journalist from the Australian Broadcasting Corporation (ABC) and two Kurds were killed, while nine others were injured.
The bombing was apparently in retaliation for the earlier US missile attack on a base of Ansar al-Islam, a radical group which Washington believed to have links to the al-Qaeda terrorist network.
The area was also regarded by the US government as a center for producing Iraqi chemical weapons.
