Baghdad - Ten days after meeting with US President George W Bush, tribal leader and head of the Anbar Salvation Council Abdul- Sattar Abu Risha was killed 50 metres away from his home Thursday in Ramadi in Anbar province, media reports said. An explosive charge targeted the Sunni Abu Risha's convoy killing him and his driver and two security guards immediately, independent Voices of Iraq news agency reported citing senior officer Mohamed al- Alwani from Ramadi police department.
Al-Alwani added that ever since Abu Risha formed the Anbar Salvation Council, which aimed at quelling the al-Qaeda terrorist network in Iraq, he had become a target of the terrorist organization.
Analysts believe al-Qaeda considered Abu Risha their second main enemy after the Americans.
Anbar Salvation Council recently announced that al-Qaeda militants had been cleared out of Anbar province, which was showcased by Bush as an example of success in Iraq. The council was supported by US- Iraqi forces.
