TEHRAN, Nov 12 (AFP) - 15h07 - Iranian border guards killed one Kurdish rebel and arrested another in clashes in the northwestern province of West Azarbayjan, the student agency ISNA reported Saturday.

"The two Pejak agents, who had entered the area for political and military purposes, had been identified by police. One was killed and another one injured and arrested in the fighting," said Mohammad-Sadegh Mohsenpour, governor of the provincial capital Oroumieh.

Pejak is a rebel group that the Iranian authorities say is linked to the Kurdistan Workers' Party (PKK), which waged a 15 year insurgency against Ankara for self rule in the Turkey's mainly Kurdish southeast.

Reports concerning major insurgent attacks by Kurds in recent months -- notably the Pejak -- have spoken of at least 120 Iranian police killed and a further 64 injured.

Tehran and Ankara are linked by an accord calling on Iran to fight the PKK and for Turkey to fight the People's Mujahedeen, an armed Iranian opposition group based in Iraq.

Iran has pointed the finger of blame at the international forces in Iraq for the recent unrest in Kurdish and Arab communities in its south-western provinces that border Iraq.
