The UN nuclear agency is investigating reports from its experts that their mobile phones and laptops may have been hacked into by Iranian officials while the equipment was left unattended during inspection tours, diplomats have told the Associated Press. One of the diplomats said the International Atomic Energy Agency was examining "a range of events, ranging from those where it is certain something has happened to suppositions", all in the first quarter of this year. He said the Vienna-based watchdog was alerted by inspectors reporting "unusual events", suggesting that outsiders had tampered with their electronic equipment. Two other diplomats in senior positions confirmed the essence of the report but said they had no further information. All three envoys come from IAEA member nations and spoke on condition of anonymity because their information was privileged. Agency spokeswoman Gill Tudor said the IAEA had no comment on the issue. IAEA inspectors tour various facilities in Iran every other week.
