Head of Kurdistan's Environment Protection Organization Kheirollah Moradi says four rangers have been killed by counter-revolutionary elements, Press TV reported.
The bodies of the rangers, who had gone for patrol on Friday, were found by a mountain climber, Moradi told ISNA on Saturday.
Explaining that the rangers had been killed by fire arms, Moradi added that "initial investigations show that this terrorist attack has been carried out by counter-revolutionary elements."
According to the investigations, the rangers' pickup truck was thrown into one of the valleys in the area, and their bodies were abandoned in the forest, Moradi said.
He said Kurdistan's military and security forces are investigating the incident to find more clues, adding that no group or individual had claimed responsibility for this terrorist attack.
