KIRKUK (AFP) - Car bombs killed four people in Kurdish areas of the disputed northern Iraqi city of Kirkuk on Tuesday, while roadside bombs killed two more in a nearby Arab town, a security official and a doctor said. The attacks come a day after top security officials from the federal government and Iraq’s autonomous Kurdistan region reached an agreement aimed at easing high tensions in disputed areas of northern Iraq, which the country’s parliamentary speaker has warned could lead to civil war. One car bomb exploded in a Kurdish area of east Kirkuk near a Kurdistan Democratic Party youth club, one of the two main Kurdish parties in Iraq, killing two people and wounding seven, a security official said.
