Iran's legislature plans to file a complaint against the US at the UN Security Council demanding the prosecution of Washington officials for their alleged open call for "terror attacks" on Islamic Republic officials.

"The Iranian nation's live and telling documents prove that the US administration as a symbol of terrorism in the world has killed millions of people and is a threat to humanity," Vice-Speaker of the Iranian parliament's Security Committee Vali Esmayeeli told the semi-official Fars News Agency on Sunday.

Citing US military operations in Iraq, Afghanistan, Vietnam, Bosnia and Herzegovina; US support of Saddam Hussein during his war with Iran; and US support for Israel - Tehran seems to believe it can prosecute Washington for a half century of geopolitics.

Esmayeeli also called on all independent countries of the world to accompany Iran in condemning the United States' "terrorist activities" at the UN.

Secretary of Iran's Supreme National Security Council (SNSC) Saeed Jalili claimed Iran would provide UN Secretary General Ban Ki-moon with documents detailing Washington’s alleged support of terrorism against Tehran.

"Iran's ambassador to the UN will in a formal letter ask the UN Secretary-General to provide other countries with the documents on the United States' management and financial backup for terrorists and put the judicial prosecution of the US administration on (the UN) agenda based on conventions," Jalili said.

"The United States has formally used its forces for terror and sabotage against Iran and other countries and as the Supreme Leader has said we have documents to discredit the United States.

Iran's Supreme Leader Ayatollah Ali Khamenei first announced on Wednesday that Iran planned to release a hundred corroborative documents substantiating Washington's role in supporting and sponsoring terrorist activities in Iran and the region.

"We have a hundred unbeatable documents on the US role in directing terror and terrorists in Iran and the region," Ayatollah Khamenei said on Wednesday.

"By releasing these documents, we will dishonor the US and those who claim to be the advocates of human rights and campaign against terrorism among the world public opinion," he added.

The remarks by Iran's Supreme Leader come as a part of the media war that has erupted in the wake of US officials accusing Tehran of plotting to assassinate the Saudi ambassador to Washington on October 11.

Washington says  US officials alleged Iran's Quds Force of the Islamic Revolutionary Guards Corps (IRGC) plotted to kill the Saudi ambassador to the US by hiring assassins from a Mexican drug cartel for $1.5 million.

But observers say Iran, which has long-established ties to the Hamas and Hizbullah terror organizations, among others, is merely trying to create a media circus to draw attention away from its nuclear program.

IAEA officials on Monday revealed Tehran had sought nuclear technology that only has military - atomic bomb - applications.

The revelation comes amid reports Israel and Britain were both considering independent strikes on Iran's nuclear program late last week.
