Eight Iranian border guards have been killed in clashes with militants near the Turkish frontier.
Iranian state television and the official IRNA news agency both reported the deaths, which came amid battles near Chaldoran in northern-western Iran on November 3.
Iribnews.ir reported that the Iranian border guards inflicted heavy casualties on the militants.
None of the reports elaborated on the affiliation of the militants, but the area near Iran's borders with Turkey and Iraq has been the scene of occasional skirmishes with Kurdish separatist groups as well as extremist Islamic militants.
Last month, Iran's Revolutionary Guards killed four militants in the area.
Iranian authorities have been often announcing crackdowns on armed groups in the last two years, claiming arrests and seizure of weapons.
