Concerns that sectarian conflict in Iraq could turn to civil war
There are fears in Iraq that the country is once again on the brink of a sectarian war. Some of the heaviest fighting in years is on-going in the west of the country.
Now, Islamist militants who have taken over the city of Fallujah are urging Sunni tribes in the area to back them in their fight against the Shia-led government of Nouri al-Malaki.
The sectarian conflict is reflected in the struggle for leadership of the insurgency in neighbouring Syria.
