Vienna: The UN's nuclear watchdog on Tuesday said that it has identified three locations in Iran where the country possibly stored undeclared nuclear material or undertook nuclear-related activities without declaring it to international observers.
The International Atomic Energy Agency (IAEA) said in a confidential report to member nations seen by the Associated Press that it has sent questions to Iran in three separate letters but has received no reply.

The IAEA had previously said that uranium particles of man-made origin had been discovered at one location outside Tehran that had not been declared, which appeared to confirm allegations made by the US and Israel about a secret nuclear warehouse.
