BOI -  Atomic inspectors have found traces of highly enriched uranium on equipment linked to an Iranian military base, raising new questions about whether Iran harbors a clandestine program to make nuclear bombs, diplomats said yesterday.

It is the second such discovery in three years of United Nations inspections in Iran. As the Security Council debates how to handle the atomic impasse with Tehran, the finding is likely to deepen skepticism about Iran's claims that its program is entirely peaceful.
