UN: No evidence Iran arming Taliban
The allegations of Iranian meddling in Afghanistan first surfaced in June, and gained momentum with senior U.S. intelligence and military officials accusing Iran of officially endorsing the shipment of armaments across its eastern border. If true, the implications for Canadian troops in Afghanistan would be serious, Foreign Minister Maxime Bernier said.
Asked whether the UN has seen any evidence of Iranian weaponry reaching the Taliban insurgency, Chris Alexander, the deputy United Nations representative to Kabul, told CanWest News Service: "None. It's the other border across which arms and weapons principally arrive."
Alexander was referring to Pakistan, Afghanistan's eastern neighbour. Link
