(BAGHDAD) -- The Iraqi government is being pressed by U.S. and United Nations officials to conduct an investigation into Saturday's attack on a refugee camp on the outskirts of Baghdad that killed at least six Iranians and wounded dozens of other people.
At least 40 rockets and mortars were fired at Camp Liberty, where 3,000 members of the People’s Mujahedeen of Iran, or the Mujahedeen-e-Khalq (MEK), are staying.
They had initially resided at Camp Ashraf, a former paramilitary camp of the 1980s near the Iranian border, but were relocated to Camp Liberty at Baghdad's insistence.
No one yet has claimed responsibility for the assault on Camp Liberty, a one-time base for American soldiers.
In Washington, the State Department condemned the "vicious and senseless terrorist attack" and demanded Iraq provide more protection for the Iranian refugees.
