Bulgarians to Dismantle Iranian Terrorist Group MKO in Iraq

...It has now been confirmed that Bulgarian troops will assume control of the formerly-armed Mojahedin-e-Khalq (MKO) organization's Ashraf camp. This move likely constitutes the final stage of removing the MKO from Iraq, a process that began with the U.S. bombing of the organization's bases in April 2003....

...This will be the first time that non-U.S. soldiers have been involved in dealing with the MKO in Iraq. Interestingly, the Bulgarians' primary task is to ensure security "inside" the camp. There is little doubt this signifies a major development relating to the status of the MKO in the near future, with the camp's complete dismantlement within 12 months a distinct possibility. After all, this is the first time coalition troops have been deployed inside Ashraf. Previously, U.S. forces have been stationed immediately outside the camp and rarely interfere in the daily routine of its inhabitants. ...

CRS, 1 Nov 06: Iran: US Concerns and Policy Responses

...U.S. forces attacked PMOI military installations in Iraq during Operation Iraqi Freedom and negotiated a ceasefire with PMOI military elements in Iraq, requiring the approximately 4,000 PMOI fighters to remain confined to their Ashraf camp near the border with Iran. Its weaponry is in storage, guarded by U.S. and now Bulgarian military personnel.

Press reports say that some Administration officials want the group removed from the FTO list and want a U.S. alliance with it against the Tehran regime. Then National Security Adviser Condoleezza Rice stated in November 2003 that the United States unambiguously considers the group as a terrorist organization. However, the debate over the group was renewed with the U.S. decision in July 2004 to grant the Ashraf detainees “protected persons” status under the 4th Geneva Convention, meaning they will not be extradited to Tehran or forcibly expelled as long as U.S. forces remain in Iraq. At the same time, some Iraqi leaders from pro-Iranian factions, including Prime Minister Nuri al-Maliki, have said that the group might be expelled from Iraq by early 2007....

I wish I could report that either of those reports were entirely correct. Regardless of the initial "plans" or intent, the MEK remains under US "custody." While they no longer have protected person status, they remain guarded by US troops in Iraq.
