"We don't have such a facility," Ali Akbar Salehi, head of the Atomic Energy Organization of Iran (AEOI), said referring to claims by the terrorist Mujahedin-e-Khalq Organization on Thursday that it had evidence of a new secret underground atomic site in the country.

"If they have any details they should inform us so that we can thank them," Salehi said.

The organization said that a uranium enrichment facility about 120 km west of Tehran was about 85% complete.

Salehi said the country has plenty of facilities using nuclear technology - for example, to sterilize agricultural products, which "do not fall into the nuclear plant category."
