TALIBAN ANTI-TANK MINES FROM U.S.

"... evidence from the US Defense Department, Canadian forces in Afghanistan and the Taliban themselves (indicates) that the increased damage to NATO tanks by Taliban forces has come from anti-tank mines provided by the United States to the jihadi movement against the Soviets in Afghanistan in the 1980s...

"according to the Pentagon agency responsible for combating roadside bombs in Iraq and Afghanistan ( JIEDDO or Joint Improvised Explosive Device Defeat Organization, a unit of the US Department of Defense), the increased Taliban threat to US and NATO vehicles comes not from any new technology from Iran but from Italian-made TC-6 mines left over from the US Central Intelligence Agency's military assistance to the anti-Soviet jihadists in the 1980s.
