A leading Al Qaida-aligned group has threatened to launch attacks on Arab leaders. The Salafist Brigade for Combat and Call warned that it would attack pro-U.S. Arab leaders and their governments. The group said the Salafists would take revenge against anybody who obeys Israel or the United States. The brigade posted its warning on the Internet during the Arab League summit in Algiers. The Salafist brigade has been regarded as the largest Islamic insurgency group in North Africa and has rarely discussed anything beyond its base in Algeria. "The apostate rulers have proved at every catastrophe that they are the roots of affliction and the symbols of treachery," Salafist leader Abu Mussab Abdul Ouadud said. "The downtrodden nation is marching with firm steps to wreak revenge on you and avenge the blood of its sons whom you have offered as sacrificial victims to America."
