Officials said about half of the insurgents captured in Samara last week were nationals from Arab states in North Africa. They said an initial interrogation has determined that the insurgents arrived from such countries as Egypt, Sudan and Tunisia. About 150 insurgents were said to have been killed in the combination of air and ground strikes by U.S. units and Iraqi forces, Middle East Newsline reported. U.S. officials said insurgents from such countries as Algeria, Egypt, Sudan and Tunisia have been recruited for operations against the Multinational Force in Iraq. They said many of the insurgents were recruited by the Salafist Brigade for Combat and Call, based in Algeria and regarded as the leading subcontractor for Al Qaida.The presence of North African insurgents was highlighted during the U.S. military operation to capture Samara, under the control of a coalition of Saddam Hussein supporters and Al Qaida-aligned agents since October 2003. The insurgents were said to have been recruited by Salafist operatives in North Africa and transported to Iraq via Syria. Many of them then joined the Tawhid and Jihad group, headed by Abu Mussib Al Zarqawi, regarded as the most lethal insurgent in Iraq. The recruits were provided with Iraqi government documents that listed their professions as everything from electricians to farmers. Officials said resistance by Saddam and Al Qaida-aligned forces continues despite the capture of Samara. They said the military has not captured the heads of the insurgency.
