Kabul: NATO launched airstrikes on Monday against Taliban insurgents who had forced government forces to abandon a district in eastern Afghanistan.
The NATO commander, meanwhile, said there is "clear evidence" that some Afghan militants have trained in Iran.
NATO reported its 50th death this month, according to a tally by a news agency - a service member killed on Sunday by a makeshift bomb in the south — as US commanders prepared to mark Memorial Day when America remembers the dead from all its wars.
Early Monday, NATO aircraft fired guided munitions on Taliban positions at Barg-e-Matal district in Nuristan, a province in the mountainous region on the Pakistani border. No casualty figures were given.
Government forces last week abandoned the district`s main town after a major assault by Taliban militants, many of them coming in from Pakistan, Afghan officials said.
Taliban strength grew in the Nuristan area after US troops abandoned an outpost where eight American soldiers were killed in a fierce attack last October.
