Tasnim � Iranian Foreign Ministry Spokesman Bahram Qassemi rejected Israeli Prime Minister�s recent speech at the United Nations General Assembly about a �secret nuclear warehouse� in Tehran and said his claims are �more like a joke�.

Speaking to reporters at his weekly press briefing in Tehran on Monday, Qassemi said what has been done by the Zionist regime of Israel against Iran is nothing but hostility and obstructionism, which has led to nothing but failure for the Israeli premier.

His behavior is more like a joke, the spokesman said, adding that this is while many countries are deeply concerned about the Tel Aviv regime�s nuclear weapons program.

In response to a question about Russian Foreign Minister Sergei Lavrov�s remarks about mediation between Iran and Israel, Qassemi said the Islamic Republic�s stance on the Zionist regime is completely clear, indicating that Iran would not accept such a mediation because it does not recognize the Zionist entity.

In a speech to the UN General Assembly on Thursday, Netanyahu said he was revealing the existence of the �atomic warehouse� for the first time in public.

As he has in past presentations, Netanyahu brought visual aids to illustrate his claims, according to media reports.

He held up a satellite image which he said showed where the warehouse was located in Tehran, and a photograph of a nondescript wall and metal gate, which he said showed the exterior of the warehouse.

Israel is the only possessor of nuclear weapons in the Middle East, but its policy is to neither confirm nor deny that it has atomic bombs. The Tel Aviv regime is estimated to have 200 to 400 nuclear warheads in its arsenal.

Unlike Iran, the Tel Aviv regime is not a member of the NPT -- whose aim is to prevent the spread of nuclear arms and weapons technology � in defiance of international pressure.
