Amir Saeid Iravani, Iran`s permanent representative to the UN

Iran`s ambassador to the United Nations says the United States is responsible for turning peaceful demonstrations in Iran into unrest and violence, according to a letter submitted to the UN Security Council.

Amir Saeid Iravani, Tehran`s permanent representative to the UN, said in the letter that Washington bears direct responsibility for "riots and violent acts" in Iran.

He condemned the United States` "illegal behavior" and its coordination with Israel to interfere in the Islamic Republic`s internal affairs.

Iravani said such interference is carried out through "threats, incitement, and deliberate encouragement of violence," to undermine Iran`s stability and security.

He said Tehran condemns the destabilizing measures that violate the UN Charter.

Iran`s Supreme National Security Council (SNSC) issued a separate statement earlier, saying the United States and Israel have continued hostile policies toward Iran following a recent 12‑day war.

The council said the Iranian people would counter sabotage efforts through national unity and solidarity.

Addressing the unrest in several cities, the SNSC said no country would tolerate insecurity imposed from the outside and insisted that the presence of security forces was aimed at restoring order.

It warned that security agencies and the judiciary would show "no leniency" toward the rioters and vandals.

The statement also pointed out that Israel has been waging "hybrid warfare" against Iran since the June war, saying recent protests, sparked by public frustration over market instability, were turned into security disturbances through foreign "guidance and planning."

The SNSC said that recent remarks by US President Donald Trump in support of the rioters exposed a joint strategy by Washington and Tel Aviv to create instability inside Iran.
