A number of Iranian police officers have been killed in separate clashes with armed groups in two of the country’s western provinces.

On Friday night, PJAK militants attacked a police station in the town of Ravansar, situated in Northern parts of Kermanshah, the Tabnak news website reported.
The report added that the exact number of casualties was still unclear.
In a similar incident, unknown armed men attacked a police base situated on a road in the outskirts of the provincial capital of Kordestan Province, Sanandaj in the early hours of Saturday morning.
During the attack, the armed group killed an Iranian police officer and injured four others.
PJAK, an offshoot of the Kurdistan Workers’ Party (PKK), has carried out a number of fatal bombings in Kurdish populated regions of western Iran and southern Turkey during the past few years.
The PKK is an armed-separatist group-- recognized by much of the international community as a terrorist group-- that carries out attacks and deadly bombing against Turkey, Iran, and Syria from its bases in the mountainous regions of northern Iraq.
According to a November 2006 article published by The New Yorker, the U.S. military and Israel provide PJAK with equipment, training and vital intelligence to destabilize the Iranian government.
