An Iranian opposition group based in Iraq said Iraqi forces are preventing passage of basic supplies to its compound north of Baghdad. The Mojahedin-e Khalq, or People’s Mujahedeen of Iran, said the blockade of Camp Ashraf began Thursday. In late January, Iraq’s National Security Advisor Mouwaffak al-Rubaie said the group must leave Iraq within two months. He added the decision to close the camp, home to about 3,500 people, was irreversible.
