Written proof of US terror plots will be released on Friday, November 4th, reported Iran's state-owned news channel Press TV.

The head of the Supreme National Security Council, Saeed Jalili, will detail the allegations during a ceremony to mark the anniversary of the 1979 US embassy hostage crisis in Tehran.

The announcement follows a claim Wednesday by Iran's Supreme Leader Ayatollah Seyyed Ali Khamenei that the US was "the greatest terrorist in the world."

He told a student rally:

"We possess 100 pieces of irrefutable evidence that reveal the US role in directing terrorists for conducting acts of terror in Iran and the region."

The supposed evidence is so explosive that it will bring down the US government, according to Iranian lawmaker Hossein Ebrahimi, Deputy Chairman of the Majlis Committee on National Security and Foreign Policy:

"Once Tehran publicizes the evidence in its possession on the US being a terrorist [state] and [Washington's] massacres, the American nation would certainly unite to topple their [ruling] regime."

Tehran has strongly denied recent claims that it backed an alleged plot to assassinate the Saudi ambassador to the US.

Foreign Ministry spokesman Ramin Mehman-Parast said the US made up the allegations in order to deflect attention from the wave of uprisings in the Middle East, as well as its own Occupy Wall Street protests, Iranian news agency Fars reported Thursday.
