Vienna, Austria - UN nuclear inspectors have returned from an inspection of a previously secret Iranian uranium enrichment site.

The Fordo site is near the holy city of Qom. Iran revealed it was building it in September 21 in a confidential letter to the International Atomic Energy Agency. Just days later, the leaders of the US, Britain and France condemned Tehran for keeping it secret.

The West believes Iran revealed the site's existence only because it had learned that the US and its allies were about to make it public. Iran denies that.

Tehran says it wants to enrich only to make nuclear fuel. But the West worries that Iran wants to create fissile warhead material. - Sapa-AP
