An Iranian opposition movement says Iraqi troops have been preventing food and fuel from entering its camp north of Baghdad for the past four days.
A statement by the People's Mujahedeen Organization of Iran said the move against Camp Ashraf is part of a pattern of harassment that has escalated under pressure from Tehran.
The Iranian government considers the People's Mujahedeen a terrorist group and has insisted that they leave Iraq. The government has assured the U.S. that none of the estimated 4,000 residents of the camp would be forced to return to Iran.
Defense Ministry spokesman Maj. Gen. Mohammed al-Askari declined Sunday to comment on the claim. The office of national security adviser Mouwaffak al-Rubaie said to call Monday.
