Iran said on Wednesday two of its Revolutionary Guards and 21 rebels were killed in a clash between government forces and the PJAK militant group.
The website of Iran's English language PressTV reported that two other Guards were injured in the fighting.
"During the clash that took place in...(northwestern) Sardasht city, two Revolutionary Guards forces were killed and two others were injured," PressTV said.
Earlier this month Iranian forces said they had seized control of a major militant base of the Free Life Party of Kurdistan (PJAK) group near the country's border with Iraq. Iran has pledged to step up military action against the group, which is seeking greater autonomy for Kurdish areas in the country.
Iranian security forces have regularly fought militants from PJAK which also has bases in the border provinces of neighbouring Iraq.
PJAK is an offshoot of the militant Kurdistan Workers Party (PKK), which took up arms in 1984 against Turkey.
