That's more than just "inappropriate", that's...well I'll let you fill in the blanks. Iran has a history of training and supporting terrorists that attack US troops in both Iraq and Afghanistan. Washington Times
KABUL, Afghanistan | The commander of NATO and U.S. forces in Afghanistan said on Sunday there is "clear evidence" that some Taliban fighters have trained in Iran.[...]
"There is, however, clear evidence of Iranian activity — in some cases providing weaponry and training to the Taliban — that is inappropriate," he said. Gen. McChrystal said NATO forces are working to stop both the training and the weapons trafficking.
Last month, Gen. McChrystal said there were indications that Taliban were training in Iran, but not very many and not in a way that it appeared it was part of an Iranian government policy. He did not give details on how many people have trained in Iran at Sunday's news conference.
A recent Pentagon report to Congress on Iran's military said arms caches found recently in Afghanistan included large amounts of Iranian weapons, including 107 mm rockets that were sent by Iran's Islamic Revolutionary Guard Corps-Qods Force. Manufacturing dates on the arms "suggest lethal support is ongoing," the report said.
