Iran Arming Taliban

British and American military sources report that Iran is now arming the Taliban with the same kind of explosively formed penetrators that it gives to Iraqi militias:

US Army General Dan McNeill, the commander of Nato forces in Afghanistan, said that the discovery of more than 50 roadside bombs and timers in lorries crossing the border from Iran last month proves that Iran’s Quds Revolutionary Guards are actively supporting the Taliban.
British special forces, believed to be from the Special Boat Service, played a prominent role in tracking and intercepting two lorries that crossed from Iran into Afghanistan’s Farah Province on Sept 5.
“I cannot see how it is possible for at least the Iranian military, probably the Quds force, to not have known of this convoy,” said Gen McNeill.

This parallels similar reports early in the summer. The ball would seem to be in our court.
