Iran has arrested 20 members of an alleged spy network in the western part of the country near the border with Iraq, the state-run news agency reported Monday. The 20 included both Iranians and foreigners who were trained by intelligence services "of the enemy," the IRNA news agency quoted the head of the intelligence department in the Kerman Shah province as saying. IRNA did not provide the official's full name or provide more details about their nationalities. IRNA, quoting the official, said the alleged spies were trained for economic, military, political, cultural and social purposes. It did not elaborate. Iran has escalated accusations against the US, saying last month that it had uncovered spy rings organized by the US and its Western allies.
