"It is clear to everyone that Iran is supporting the enemy of Afghanistan, the Taliban," Col. Rahmatullah Safi, the head of border police for western Afghanistan, told The Sunday Times of London.
A Baluch tribesman in southern Afghanistan is believed to be the middle man between Iran and the Taliban, Afghan intelligence sources told The Times. The middle man also uses Iran as the central point for heroin smuggled out of Afghanistan to Europe, the report said.
Col. Thomas Kelly, a U.S. Army commander with NATO, said the armor-piercing weapons crossing the border appear factory made.
"These are very sophisticated (improvised explosive devices) and they're really not manufactured in any other place to our knowledge than Iran," Kelly said.
