Iranian border guards clashed Sunday with the Afghan Taliban, Iranian media reported, the latest cross-border exchange since the former insurgents seized power in neighboring Afghanistan a year ago. The official IRNA news agency quoted Meisam Barazandeh, governor of the border country of Hirmand in eastern Iran, as saying that the incident is under investigation. He did not provide details about the clash or report any casualties. There was no immediate comment from the Taliban. Irans semiofficial Tasnim news agency, which is close to Irans powerful Revolutionary Guard, said the Taliban opened fire on houses on the eastern edge of the county, in the area of Shoqalak, across the border from Afghanistans Nimruz province. The report said also that Taliban forces tried to raise the Taliban flag in an area that is not part of the territory of Afghanistan and that after the exchange, calm returned. Clashes have repeatedly erupted between Iranian security forces and Afghan Taliban forces in various spots along the border since the Taliban takeover in Afghanistan last August. The exchanges of fire are often over local issues such as disputes over farmland, water or smuggling, and usually end quickly. In some of the worst clashes, last December, the Afghan Taliban seized several checkpoints on the Iranian side but soon withdrew, and both sides called the incident a “misunderstanding.”
