Iran to respond to U.S. strike with global terror?

Iran would respond to U.S. military strikes against its nuclear sites with global attacks by intelligence operatives and Hezbollah teams, The Washington Post reported in an article on its Web site on Saturday, citing unnamed "intelligence and terrorism experts." Iran would attack U.S. targets in Iraq and there is "growing consensus that Iran's agents would target civilians in the United States, Europe and elsewhere," The Post said.

"U.S. officials would not discuss what evidence they have indicating Iran would undertake terrorist action," it said. But the article quoted one "senior official" as saying that the matter is "a huge issue" and another saying it "is consuming a lot of time" in the U.S. intelligence apparatus. Intelligence officials declined to say whether they have detected "preparatory measures" by Iran's foreign-based operatives, such as more surveillance, counter-surveillance or message traffic, The Post said.

The Post article comes amid increased international tension over Iran's nuclear program, which some nations say is aimed at building atomic bombs. Iran says the program is civilian.
