Iran's state-run satellite Press TV reported Thursday that Iran will reveal some documents about the " U.S. anti-Tehran terror plots."

Iran's chief nuclear negotiator Saeed Jalili will reveal details about the U.S. involvement in anti-Iran terror plots in his speech on Friday as the country marks the anniversary of the seizure of former U.S. embassy in Tehran 32 years ago.

In 1979, a group of Iranian students seized the U.S. embassy in Tehran and captured some 60 U.S. diplomats, with 52 of them in captivity for 444 days during the hostage crisis.

Supreme Leader of the Islamic Republic Ayatollah Sayyed Ali Khamenei said Wednesday that "we have one hundred undeniable documents (which proves) that the U.S. government is behind terrorist attacks in Iran and the region."

Khamenei said that Tehran will reveal those documents to " disgrace the U.S. government."

The United States recently wanted to save itself from the domestic pressures by making "absurd scenario" against the Islamic Republic and to pressure Iran, said the Iranian leader.

The tension between Tehran and Washington was escalated after the United States accused last month the Islamic Republic of being involved in terror plots in the U.S. soil.

The United States said that Manssor Arbabsiar, a 56-year-old U. S. citizen holding both Iranian and U.S. passports, and Gholam Shakouri, a member of the Qods Force affiliated to Iran's Islamic Revolution Guard Corps (IRGC), were charged with sponsoring and promoting terrorist activities abroad, including a plot to assassinate the Saudi ambassador to the United States.

Arbabsiar was arrested by the U.S. authorities, while Shakuri remains in Iran.

In a statement issued on Wednesday, 240 Iranian lawmakers expressed their strong support for the IRGC and Qods Force, in a response to the U.S. accusations that Shakouri was linked to the Qods Force.

The Qods Force has proven its capability of safeguarding the achievements of the Islamic Revolution, the lawmakers said in the statement, "We as signatories to the statement ... (to) express our appreciation and strong support for IRGC forces, particularly the Qods Force."

Iranian Foreign Ministry spokesman Ramin Mehmanparast said Wednesday that "the Americans are bewildered and confused in their decisions and behavior in the face of the regional revolutions."

He argued that the recent U.S. allegations of Tehran's involvement in a terror plot to assassinate the Saudi envoy were related to the U.S. loss in the region and aimed at deflecting the public opinion from the wave of popular protests in the region.

The spokesman said the majority of the American public will not accept the Washington-fabricated scenario against the Islamic Republic.

A U.S. House committee on Wednesday approved tougher sanctions on Iran, targeting its central bank in a bid to further isolate the country from the international community.

The House Foreign Affairs Committee Chairwoman Ileana Ros- Lehtinen said the effort, following Iran's alleged involvement in the plot to assassinate the Saudi ambassador, is meant to "clamp new and tougher sanctions on Iran's energy sector, threatening the regime's existence if it refuses to halt its nuclear weapons program."

The United States has been working on tougher sanctions on the Iranian central bank for a while. In October, U.S. Under Secretary of Treasury for Terrorism and Financial Intelligence David Cohen said at a hearing at the House Foreign Affairs Committee that the U.S. was seeking multilateral support in an effort to impose additional sanctions on Iran's central bank.

The new sanctions, according to Cohen, will have "a potentially powerful impact on Iran."
