I saw this mentioned by gulliani this afternoon on FOX. So I looked it up and found this:

The Iranian Resistance Calls for deployment of Blue Helmets in Camp Liberty and securing minimum protections

NCRI - In a series of recent remarks, leaders of the Iranian regime have described the Iranian opposition, the People's Mojahedin Organization of Iran (PMOI/MEK) as a threat to the regime's security and stressed that its centers must be destroyed, it members must be executed, and any country accepting them should be sharply criticized.

This is while they repeatedly expressed their gratitude to the government of Iraq for the September 1 massacre of 52 PMOI members in Camp Ashraf.

Mansour Haghighatpour, deputy chair of National Security and Foreign Policy Commission in the regime's parliament who is also a commander of the terrorist Qods Force, explained objectives of the September 1st massacre in Ashraf: “Cleansing [massacring residents] of Camp Ashraf in Iraq strengthens national security in our country.” The statement clearly displays the Iranian regime’s profound fear of the PMOI.
This is the same MEK that was taken off the terrorist list and has been the main source for getting information out of iran concerning the nuclear development and other intelligence information. It seems iraqi forces did nothing to stop this slaughter. Neither did the un who are running the camp. But hey, our DiC is going to hold talks with the iranians about their nukes.
