[Bangla Daily Star] The UN nuclear watchdog chief said yesterday talks with Iran have been "going around in circles" -- unusually blunt criticism pointing to rising tension over suspected nuclear arms research by Tehran that has increased fears of a new Middle East war. Yukiya Amano, director general of the International Atomic Energy Agency, vented growing frustration at the lack of results in getting Iran to address suspicions of military dimensions to its atomic energy program. Tehran denies the accusations.
