Meanwhile, the official count of Iraqi deaths rose 15 percent over February to more than 2,000. At least 600 Iraqis have been killed in the last week. The death toll from last week’s suicide truck bombing in Tal Afar has now risen to make it the single deadliest attack since the U.S.-led invasion. At least 152 people have now been counted dead. The count rose as rescue workers continued to find bodies beneath the rubble. Another 45 people died when Shiite police went on a revenge attack in Sunni areas.
