Iran has been teaching Taliban commanders to plant improvised explosive devices (IEDs) and mount ambushes to kill NATO troops in Afghanistan, the Times of London reports. The Taliban leaders say Iran paid for the training, a three-month course, over the winter, when they were sneaked into the southeast Iranian city Zahidan. There, they were taught by a plainclothes instructor in the first month how to attack convoys and escape. Then they were taught how to plant IEDs so that one group of soldiers is killed in one bomb wave and their rescuers are killed in another. Finally, they learned how to charge NATO bases and checkpoints. Western officials say the crackdown on Pakistani support for the Taliban has led the insurgent group to get aid elsewhere.
