Eight members of the rebel Kurdish Democratic Party of Iran (KDPI) have been killed in clashes with security forces along the Iraqi border, state media reported Wednesday. Border guards fought the group overnight and into Wednesday morning in the north-western province of West Azerbaijan, the IRNA news agency said. The clashes lasted several hours, and the security forces did not sustain any casualties, a local governor told IRNA. The KDPI, formed in 1945, is the oldest Kurdish political party in Iran.
