According to information received by Iran International, Iranian-backed Iraqi militias began recruiting fighters four days ago to help the Islamic Republic's forces suppress protests in Iran. So far, around 800 Iraqi Shiite militiamen have been deployed, almost all of them members of Kataib Hezbollah, Harakat al-Nujaba, Sayyid al-Shuhada and the Badr Organization.
The information indicates that Iraqi government officials are aware of the mobilization of forces to assist Tehran. The transfer of these fighters is said to be taking place through the Shalamcheh, Chazabeh and Khosravi border crossings, under the cover of “pilgrimage trips to the holy shrine of Imam Reza in Mashhad.” In practice, the forces reportedly gather at a base linked to Khamenei base in Ahvaz before being dispatched to various regions to take part in the violent crackdown on demonstrations.

Many Iranians fought in the war against Iraq, and many have served in the military, so when they gain access to weapons, they will hunt down these henchmen of death from Iraq.
I don’t think they can sink any lower than hiring Iraqis to kill Iranians
