Iraqi oil exports have ground to a halt after a series of attacks on two key oil pipelines in southern Iraq.
Officials say damage caused by blasts over the past three days could take more than a week to repair, shutting down daily crude exports of about 1.6 million barrels from southern terminals near the city of Basra.
In another blow to Iraq's oil industry, police say gunmen in Kirkuk killed Ghazi Talabani, the top security official for the state-run Northern Oil Company.
North of Baghdad, in Balad, the U.S. military says three American soldiers were killed and 25 people injured in a rocket attack near a U.S. base.
And in the town of Ramadi, west of the capital, a roadside bomb has killed six Iraqis, including a policeman. Seven Iraqis, including six members of the Iraqi Civil Defense Corps, were arrested for alleged involvement in the blast.
