BAGHDAD (AFP) - A senior US commander said on Saturday that Al-Qaedas ability to infiltrate foreign fighters into Iraq had been severely restricted, but that it was still a threat and would remain so. Brigadier General Jeffrey Buchanan said that a deadly attack in Baghdad targeting Christians and explosions in Shia neighbourhoods across the capital over the past week demonstrated that Al-Qaeda remained deadly. The attacks demonstrate that Al-Qaeda remains determined and dangerous, said Buchanan, director for strategy for US forces in Iraq. He said that American and Iraqi forces had degraded Al-Qaedas ability to plan and coordinate attacks, raise finance and recruit fighters inside Iraq. But I think Al-Qaeda remains a threat and will continue to remain a threat in the future, he said at an informal round-table discussion with journalists in Baghdad. Asked about reports that foreign militants were involved in the assault on the cathedral, Buchanan said Al-Qaedas flow of foreign fighters joining its ranks had slowed to a trickle. We have had a significant impact on degrading the network that Al-Qaeda used to bring foreign fighters from other countries. But it has not been shut off, he said. There are still a small number of foreign fighters that have been and continue to come across the border. Dominantly they have come through the Syrian border, but that does not mean they originate there. Survivors said that of the five gunmen who stormed the cathedral in the Karrada district in central Baghdad, only one was Iraqi, another apparently had a Syrian accent and three others spoke in a different Arabic dialect. Buchanan said that Al-Qaeda was slipping in only five to 10 percent of the number of fighters it was bringing into Iraq a few years ago, without giving any figures.
