TEHRAN, July 21 (Xinhua) -- The Kurdistan Free Life Party (PJAK) claimed responsibility for a clash on Saturday, killing 11 forces of Iran's Islamic Revolution Guards Corps (IRGC), PJAK spokesperson Amed Shaho told Rudaw Media Network.
Eight other IRGC forces were injured in the clash with Kurdish militant groups in west of Iran, official IRNA news agency reported.
The "terrorist" attack targeted a military base in Dari village near Marivan city in Kurdistan province, the report said.
The PJAK said it launched the attack in retaliation to the killing of its forces and the assassination of one of its members in the Sulaymaniyah province of the Iraqi Kurdistan Region.
The PJAK, an anti-Iranian Kurdish rebel group, is linked to Turkey's outlawed Kurdish Workers' Party (PKK).
Iran's western Kurdistan province has been the scene of bloody clashes between the Iranian security forces and the Kurdish rebels during the past years.
