Iran and Iraq have signed an extradition agreement, the latest step in warming relations between the neighboring countries, which fought a war in the 1980s.
The accord was signed by the justice ministers of both countries in Tehran on April 24.
Iranian media speculated the agreement would be used to extradite exiled Iranian militants back to Iran, where they are considered terrorists. But Iraqi Deputy Justice Minister Busho Ibrahim said the deal would not be used to repatriate members of the People's Mujahedin because it "concerns criminals."
Earlier this month, Iraqi forces raided Camp Ashraf, home to the group which wants to overthrow the Iranian government.
According to the UN, 34 people were killed during the April 8 raid on the camp, which was set up under Saddam Hussein but which the new Iraqi government wants to close.
