Washington, Oct 13: Some of the al-Qaeda operatives whose activities led to a US security warning last month have been captured, while others remain at large, US counter-terrorism authorities say. "We have received a lot of good information from these detainees over the past several weeks and corroborated the fact there were active plans, ongoing, to conduct another attack in the United States," said William H Parrish, a top intelligence official with the Homeland Security Department, during a recent interview with the Associated Press.

"This attack as they indicated was probably going to be multiple attacks, simultaneous," he said. The al-Qaeda member include some lieutenants operating in Saudi Arabia. Their leader, Abu Bakr Al-Azdi, turned himself in June; his deputy was killed in a recent shootout with Saudi forces.

"We also know there were also other members involved with this planning that are still loose," Parrish said. Parrish, the acting assistant secretary for information analysis at Homeland Security, said the threat posed by this group remains one of the top domestic terrorism concerns.
