The Islamic Revolution Guards Corps (IRGC) managed to destroy the biggest compound of Party for Free Life of Kurdistan (PJAK) terrorist group in northwestern Iranian city of Sardasht late Saturday, IRNA reported.
An informed source told IRNA on Sunday that five of the militants were killed in the operation, launched by the IRGC against the terrorists.
"Bodies of the five terrorists are being transferred to Sardasht," added the source.
He said the operation was held in Amirabad region in Vazineh district in Sardasht, lasting from late Saturday until Sunday dawn.
"Another PJAK agent, who was injured in the operation, is seized by the IRGC," the source added.
The source said that "the biggest base of the anti-revolutionary forces 50 kms from Sardasht on the zero border point is now under the IRGC control."
The source concluded that in the operation the PJAK forces left behind considerable amounts of ammunition and various heavy machine-guns before fleeing the scene of clash.
Members of the terrorist PJAK group -- an offshoot of the Kurdistan Workers' Party (PKK) -- regularly engage in armed clashes with Iranian security forces along the country's western borders with Iraq's semi-autonomous Kurdistan region.
Recognized as a terrorist group by Turkey, Iran, Iraq, the United States, the European Union, and the United Nations, the PKK is responsible for many deadly operations in northern Iraq and southern Turkey.
Both terrorist organizations launch their attacks from Iraq's Qandil Mountains in the areas under the control of KRG.
