Iran has denied allegations by an exiled opposition group that said Tehran has a secret nuclear weapons facility.
A top Iranian diplomat for nuclear affairs told reporters Thursday the site in question has nothing to do with nuclear activities. He said Iran has no undeclared nuclear facilities.
On Wednesday, the opposition National Council of Resistance of Iran alleged that Tehran has a secret uranium enrichment facility and has imported weapons-grade uranium and blueprints for a nuclear bomb.
But Tehran says its nuclear programs are strictly for electricity generation.
A recent International Atomic Energy Agency report said Iran has not diverted nuclear materials to a weapons program, although it did not rule out the possibility of secret atomic activities.
