Kabul: The commander of NATO and US forces in Afghanistan said on Sunday there is "clear evidence" that some Taliban fighters have trained in Iran.
General Stanley McChrystal told reporters in the Afghan capital that Iran - Afghanistan`s western neighbour - has generally assisted the Afghan government in fighting the insurgent group.
"There is, however, clear evidence of Iranian activity - in some cases providing weaponry and training to the Taliban - that is inappropriate," he said. McChrystal said NATO forces are working to stop both the training and the weapons trafficking.
Last month, McChrystal said there were indications that Taliban were training in Iran, but not 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.
The US command confirmed that an American service member was killed on Sunday in a small arms attack in southern Afghanistan. May is already the deadliest month this year for US troops with 33 deaths - two more than in February when American, NATO and Afghan forces seized the Taliban stronghold of Marjah in Helmand province.
The month also brought the 1,000th US military death in the Afghan war since it began in 2001 when Marine Cpl Jacob Leicht was killed on Thursday by a roadside bomb in Helmand.
