The US has branded as "complete nonsense" Iran's accusation that its enemies have been behind a wave of violent protests sweeping the country, BBC reported.
Iran's Mullah leader Khamenei had made the accusation in his first comments on the protests.
Khamenei said: "In recent days, enemies of Iran used different tools including cash, weapons, politics and intelligence services to create troubles for the Islamic Republic."
The dignity, security, and progress of the Iranian nation is owed to the self-sacrifice of the martyrs. What prevents enemies from exerting their atrocities is the spirit of courage, sacrifice, and faith within the nation.

Analysts say the ayatollah's reference to "enemies" is a swipe at the US and regional rival Saudi Arabia.
US envoy to the UN Nikki Haley said the accusation was "ridiculous".
She added: "The people of Iran are crying out for freedom, All freedom-loving people must stand with their cause."
Haley said the protests were "spontaneous", adding that the US planned to call an emergency UN meeting on the situation.
The Security Council deals with international threats to peace and security and it is unclear if there would be enough support among council members for such a meeting.
Haley continued: "The freedoms that are enshrined in the United Nations charter are under attack in Iran. Dozens have already been killed. Hundreds have been arrested.
"If the Iranian dictatorship's history is any guide, we can expect more outrageous abuses in the days to come."
For the sixth straight day, protesters have been pouring onto streets across Iran, demanding the change of the entire regime.
Iranian citizens express their rage over the Mullah's regime crimes and schemes that deteriorated the economic, social and other situations of the citizens.
