To make matters worse, the Communist Tudeh Party, which supported the Soviet Union and had attempted to kill the Shah only four years earlier, began to infiltrate the military and send mobs to "support Mosaddegh" (but in reality to marginalize all non-Communist opponents). Earlier, the Tudeh had denounced Mosaddegh, but by 1953 they changed tack and decided to "support" him. The Tudeh violently attacked opponents under the guise of helping the prime minister (the cousin of the future queen of Iran, Farah Pahlavi, was stabbed at the age of 13 in his school by Tudeh activists), and unwittingly helped cause Mosaddegh's reputation to decline, despite the fact that he never officially endorsed them. However, by 1953 he and the Tudeh had formed an unofficial alliance of convenience with each other; the Tudeh were the "foot soldiers" for his government, effectively replacing the Fadaiyan in that role, all the while secretly hoping that Mosaddegh would institute communism. Pro-Shah mobs also carried out attacks on Mosaddegh opponents, and there may have been some CIA coordination.
