Press TV - The UN nuclear agency says it has inspected a site in Tehran which�Israeli PM�Benjamin Netanyahu last year described as a �secret atomic warehouse� but it turned out to�be a carpet cleaning facility.�

Netanyahu claimed�at the United Nations in September that the site�housed 15 kg of unspecified radioactive material, citing it as testimony to his frivolous allegations that�Tehran sought to obtain nuclear weapons.

Such reports do not please Israel which�has been�stealing�nuclear secrets and covertly making bombs since the 1950s.

Israel's nuclear program�has been an open secret since a disgruntled technician,�Mordechai Vanunu, blew the whistle on it in 1986, but the official Israeli position is still never to confirm or deny its existence.

Israel also makes controversial claims against Iran's nuclear program from time to time, which are often met with ridicule.

Netanyahu�s most recent spectacle at the UN in September�drew swift reaction on social media, with Twitter users posting largely derisive comments.

After the speech, many Iranians took selfies in front of the carpet cleaning center in Turquzabad which Netanyahu claimed was a "secret atomic warehouse".
