A suicide bomber detonated his explosive vest outside a tribal leader's house in Iraq's Anbar province killing six people, while three people have died in other violence.
The suicide bomber launched the attack late afternoon at a checkpoint outside the sheikh's rural homestead near the city of Fallujah, 50 kilometres west of Baghdad.
At least four people were wounded in the blast.
The incident occurred when tribal leaders had gathered to welcome some prisoners who had been freed a few hours earlier by the US military.
The tribal leaders are members of the so-called Awakening front against Al-Qaeda, which has been credited with largely turning around the security situation in the province, once a hotbed of insurgency..
In another attack today in Baquba, unidentified gunmen opened fire on a group of Awakening members, killing one of them.
At Saad Camp, about five kilometres west of Baquba, a roadside bomb struck a civilian car killing two people.
