At least 31 people have been killed in suicide car bombings near Kirkuk in Northern Iraq. The attacks targeted a checkpoint manned by Kurdish forces. The Kurds moved into Kirkuk after the Iraqi army abandoned its posts in the face of the Sunni rebellion, which began last month. And as the Kurds take new territory they are facing new dangers.
