US military and special-operations teams "have escalated their activities in Iran to gather intelligence" and reportedly "have also crossed the border in pursuit of Iranian operatives from Iraq," according to investigative reporter Seymour Hersh in an article in the March 5 issue of The New Yorker magazine.
Hersh quotes a former senior intelligence aide stating: "The word went out last August for the military to snatch as many Iranians in Iraq as they can. They had 500 locked up at one time. We're working these guys and getting information from them."
The intelligence source added, "The White House goal is to build a case that the Iranians have been fomenting the insurgency and they've been doing it all along - that Iran is, in fact, supporting the killing of Americans."
Hersh said a Pentagon consultant confirmed the intelligence aide's statement that hundreds of Iranians have been captured by American forces in recent months.
