Civil war is raging across central Iraq, home to a third of the country's 27 million people. As Shia and Sunni flee each other's neighbourhoods, Iraq is turning into a country of refugees.
The UN High Commissioner for Refugees says that 1.6 million are displaced within the country and a further 1.8 million have fled abroad. In Baghdad, neighbouring Sunni and Shia districts have started to fire mortars at each other. On the day Saddam Hussein was sentenced to death, I phoned a friend in a Sunni area of the capital to ask what he thought of the verdict. He answered impatiently that "I was woken up this morning by the explosion of a mortar bomb on the roof of my next-door neighbour's house. I am more worried about staying alive myself than what happens to Saddam."
Iraqi friends used to reassure me that there would be no civil war because so many Shia and Sunni were married to each other. These mixed couples are now being compelled to divorce by their families. "I love my husband but my family has forced me to divorce him because we are Shia and he is Sunni," said Hiba Sami, a mother, to a UN official. "My family say they [the husband's family] are insurgents ... and that living with him is an offence to God." Members of mixed marriages had set up an association to protect each other called the Union for Peace in Iraq but they were soon compelled to dissolve it when several founding members were murdered.
