Guess who's training the Taliban in how to use roadside bombs

According to the commanders, Iranian officials paid them to attend three-month courses during the winter.

They were smuggled across the border to the city of Zahidan, in southeast Iran, an hour’s drive from training camps in the desert.

Instructors in plain clothes provided daily exercises in live firing. The first month was devoted largely to teaching the Taliban how to attack convoys and how to escape before Nato forces could respond.
