Hundreds of supporters of an Iranian opposition group have rallied in Stockholm, denouncing the Islamic Republic\'s regime and urging the UN to better protect the group\'s members in neighboring Iraq, ABC News network said. Former US Congressman Patrick Kennedy was among the speakers on Saturday at the demonstration in support of the Mujahedin-e Khalq, or MEK. The crowd waved Iranian flags and chanted \"down with Mullahs\' regime\" before marching toward the Swedish Parliament. The MEK fought alongside Saddam Hussein\'s forces in the Iran-Iraq war and until recently was listed by the US as a terrorist organization. The group says it  enounced violence in 2001. The UN says more than 3,000 MEK members live at a former US military base in Iraq. Iraq still considers MEK a terrorist group and wants it out of the country.
