"The Iranian regime's recent actions underscore that its aggression constitutes a direct threat not only to Israel, but to regional and international peace and security," Gideon Saar posted on X.

"I urge the UN Security Council to condemn Iran and immediately designate the IRGC as a terrorist organisation," he added, addressing a letter to the US ambassador to the UN, Mike Waltz, who is the current president of the Security Council.

The IRGC was created after the 1979 revolution to protect the Islamic republic, with a stated mission to "guard the revolution and its achievements".

The influence of the IRGC extends into politics and business, where it is a major player with involvement in most sectors of Iran's sanctions-hit economy.

The IRGC answers to Iran's supreme leader and boasts its own ground, naval and air forces.

The United States and Israel launched strikes on Iran on February 28, killing its supreme leader and plunging the Middle East into a spiralling war.

The US has already designated the Iran Guards a "terrorist organisation", with the European Union following suit in January over a deadly crackdown on mass protests.
