Iraqi security forces have stormed the base of the terrorist Monafeqin grouplet named as the Mujahedin-e-Khalq Organization (MKO).
An Iraqi military official has said that Iraqi forces have taken complete control of the camp.
Four people were killed and 300 wounded when Iraqi soldiers and police stormed Camp Ashraf on Tuesday.
The base is located in Diyala province, north of Baghdad, and is home to around 3,500 MKO members and their families.
"After the failure of negotiations with the Mujahedeen (Khalq) to enter peacefully, the Iraqi army entered Camp Ashraf with force and it now controls the camp and all entrances to it," an Iraqi military source said.
An Iraqi police official has announced that about 50 camp residents have been detained.
The MKO was founded in Iran in the 1960s, but its top leadership and members fled the country in the 1980s after carrying out a series of assassinations and bombings inside the country.
The group is especially notorious in Iran because they allied with former Iraqi dictator Saddam Hussein during the 1980-1988 Iran-Iraq war.
America, Canada, Iraq, and Iran have all designated the MKO as a terrorist organization.
The European Union had also designated the MKO as a terrorist organization but inexplicably removed it from the EU terror list in January 2009.
US military officials in Iraq say they were not informed about the plan until after it was carried out.
