VIDEO - Syrian Foreign Minister Walid Muallem accused the United States on Monday of carrying out a "terrorist aggression" on Syria after a deadly raid which Damascus said killed eight civilians. "The Americans do it in the daylight, this means it is not a mistake, it's by blunt determination. For that we consider this criminal and terrorist aggression," Muallem told a news conference in London. He said Syria will ask the United States and Iraq for an investigation into the attack, which took place in the Albou Kamal area in eastern Syria on Sunday. Meanwhile a US counterterrorism official said the head of a Syrian network that funneled foreign fighters, weapons and cash into Iraq was killed in the raid. The official, who spoke on condition of anonymity to discuss sensitive intelligence, named the man as Abu Ghadiyah, and called him the single most important foreign fighter cell that has bedeviled Iraq since the US invasion in 2003. Meanwhile, a Syrian news site released a video documenting the attack. According to the US, special forces carried out the attack against a smuggling network of foreign fighters from northern Africa and other areas in the Middle East into Syria and from there to Iraq. The Americans had failed to block the smuggling network because it was operating from the Syrian side of the border. Eight people were killed in the strike, all Syrian citizens, including a man and his four children and a couple. The Associated Press, Reuters and Roee Nahmias contributed to the report
