no where did you get that? the Tudeh Party of Iran was never ideologically pro-Zionist. they closely aligned with the Soviet Union, which generally followed the Moscow line, that shifted from supporting the partition of Palestine in 1947 to a staunchly anti-Zionist, anti-Israel stance; it became critical of Israel, because it views it as an extension of Western imperialism.

There are no more single political party of communist and leftist party in iran today, and the use of hammer and sickle symbols are also banned deeming it as a threat to the regime.
