Press TV - Millions of Iranians from all walks of life have thronged the streets across the country to celebrate the 41st anniversary of the Islamic Revolution, which toppled the US-backed Pahlavi regime in 1979.

In Tehran, large groups of people, braving freezing temperatures, are taking 12 major routes across the capital leading to the iconic Azadi (freedom) Square, which played host to many of the anti-Pahlavi protests in the run-up to the Revolution.

President Hassan Rouhani is slated to deliver a speech to the demonstrators at the venue later in the day.

Iranians in other cities, towns and villages are also attending similar rallies en masse to renew their allegiance to the ideals of Imam Khomeini, the late architect of the Revolution and founder of the Islamic Republic.

Every year, the demonstrators�chant slogans against the US and burn American flags�to condemn the highly hostile agenda that Washington�has been pursuing against the Iranian nation over the past four decades.

This year�s mass rallies are especially significant as they coincide with the 40th-day memorial for Lieutenant General Qassem Soleimani, the former commander of the Quds Force of Iran�s Islamic Revolution Guards Corps (IRGC), who was assassinated together with his comrades in a US drone strike in Baghdad in early January.

The targeted killing of General Soleimani � the Middle East�s most prominent anti-terror commander � has sent anti-American sentiment soaring not only in Iran but also among regional nations.

In the capital, Iran�s Ministry of Defense and Armed Forces Logistics held an exhibition on the sidelines of the rally, putting on display a number of the country�s defense achievements, including smart bombs, precision-strike missiles and armored personnel carriers, in a show of power amid enemy threats.

General Soleimani�s martyrdom on January 3 took US-Iran tensions to a new level, with Tehran vowing �harsh revenge.� Days later, Iran�s Armed Forces launched retaliatory ballistic missile strikes against two US military bases in Iraq.

America�s act of state terrorism has given rise to calls in Iran and other neighboring countries for the US military to end its military presence and meddling in the Middle East.

The tensions first began to escalate in May 2018, when the administration of President Donald Trump pulled the US out of a multilateral nuclear deal with Tehran and unleashed a campaign of �maximum pressure,� which is mainly taking aim at the Iranian economy.

Anger at Trump�s �already-failed� Mideast plot

Meanwhile, the Iranian demonstrators are taking the occasion to voice their outrage at a contentious plan recently unveiled by the Trump administration with the aim of ending the decades-long Israeli-Palestinian conflict.

The plot � which the Palestinians have unanimously rejected � is meant to help the Israeli regime consolidate its occupation of the Palestinian territories in a blatant violation of international law.

Additionally, Iran�s Intelligence Minister Mahmoud Alavi issued a statement, saying that during the rallies, the Iranians�will express their opposition�to the �already-failed deal of the century.�

During the rallies in Iran, the demonstrators shouted slogans against the anti-Palestine plot, burning US and Israeli flags and hanging Trump�s effigies.
