At least 10 people were killed after two bombs exploded near a checkpoint run by government-allied Sunni group in western Iraqi city of Ramadi, police and medics have said.
The first explosion killed a police officer and the second bomb went off five minutes later as police and bystanders gathered around the wreckage in the Sunni heartland of Anbar, which shares a border with Syria.
“We were on duty at a nearby checkpoint when the car exploded. We ran to work out what was going on, but before we reached the car it exploded again,” said a policeman at the scene.
Police and hospital officials said at least 22 people were wounded in the attack on the checkpoint which was run by Sahwa, a Sunni group that joined forces with the US troops to fight al-Qaeda during the Iraq War.
Since then, the group has been a target for Sunni fighters who consider its members traitors.
More than 1,000 people died in attacks across Iraq in May alone, making it the deadliest month since the worst of the sectarian bloodletting more than six years ago.
