Al-Qaida in Iraq has claimed responsibility for Thursday's bomb attack that killed Sunni tribal leader Sheikh Abdul Sattar Abu Risha -- a key U.S. ally in Iraq.
The group made the claim in an Internet statement Friday. The attack on Abu Risha near his home in Ramadi in al-Anbar province has been widely blamed on al-Qaida in Iraq. Earlier Friday, mourners at Abu Risha's funeral called for revenge.
Iraqi police and U.S. military vehicles lined the route of the funeral procession. Last year, Abu Risha organized Sunni Arab clans (under the umbrella of the Anbar Awakening Council) to fight al-Qaida in Iraq. He was killed a little more than a week after meeting in Anbar province with President Bush. U.S. and Iraqi officials credited Abu Risha with helping stem the violence in the province. In other news, the U.S. military says a roadside bomb blast killed four U.S. soldiers in Diyala province, east of Baghdad.
