At least 21 people have been killed by a car bomb in northern Iraq.
Up to 50 others were wounded by the bomb in a vegetable market in Tal Afar, north-west of Baghdad on Friday.
The market was crowded with shoppers.
The town is in a region where al-Qaeda is said to have regrouped since being forced from Baghdad.
The attack was the biggest since suicide bombers struck Shi'ite pilgrims in Baghdad last month.
