The militant organization that was once the scourge of the U.S. military campaign in Iraq and probably is responsible for more than 100 deaths in the country over the last few days has set its sights on launching attacks in the United States, intelligence officials said.
Al Qaeda in Iraq released a message this week that threatened to strike at the “heart” of the United States, and several associates of the group have been arrested in the U.S. and Canada in the last two years, said American officials, a sign that the organization has tried to establish a network in North America.
