Two militant groups said Sunday they have named a new spokesman to silence those who claim to speak for the insurgency. In a joint statement posted on an Islamic Web site, the Islamic Army in Iraq and the Army of Mujahedeen said they had chosen Ibrahim Youssef al-Shammari as their spokesman. The little-known al-Shammari appeared on the Arab satellite channel Al-Jazeera on Sunday "to silence all those who talk in the name of the mujahedeen," the groups said in a statement posted on an Islamic Web site.During an appearance on Al-Jazeera, al-Shammari said the resistance "has a realistic and truthful political project," adding that the groups were in talks with other armed factions to come up with a unified position. He did not elaborate. Al-Shammari argued that sectarian problems were created after the U.S.-led occupation of Iraq in order to prolong the presence of foreign troops. Last week, a Web statement issued in the name of The Islamic Army in Iraq, the Army of Mujahedeen and the Ansar al-Sunnah Army threatened the life of a Sunni Arab politician, Ayham al-Samarie, who announced the formation of a political group he claims represents the demands of an umbrella organization of insurgents. The three groups accused the dual U.S.-Iraqi national of spreading lies.
