U.S.: NATO has intercepted Iranian arms

Just how much more of this are we going to take?

PARIS - NATO has intercepted Iranian weapons shipments to Afghanistan's Taliban insurgents, providing evidence Iran is violating international law to aid a group it once considered a bitter enemy, a senior U.S. diplomat said Wednesday.

"There's irrefutable evidence the Iranians are now doing this," Undersecretary of State Nicholas Burns said on CNN. "It's certainly coming from the government of Iran. It's coming from the Iranian Revolutionary Guard corps command, which is a basic unit of the Iranian government."

Speaking separately to The Associated Press, Burns said NATO must act to stop the shipments. The Iran-Afghanistan frontier is "a very long border. But the Iranians need to know that we are there and that we're going to oppose this."

"It's a very serious question," he said, adding that Iran is in "outright violation" of U.N. Security Council resolutions.
