A prominent Sunni Arab group charged Friday that some officials in the Iraqi government have links with Shiite militias involved in sectarian violence and said authorities should be held responsible for any attacks by the armed groups.
The Iraqi government said the group's claims were false and could incite rebellion.
A Sunni clerical group, the Association of Muslim Scholars, said it had obtained information that militias were planning to attack neighborhoods in Baghdad, in line with bloody assaults this year pitting members of Iraq's majority Shiites against Sunni Arabs who dominated the country under Saddam Hussein.
"We also have come to know that some officials in this government know of this criminal scheme, which raises suspicions that they are collaborating with these militias," the association said.
"The Association of Muslim Scholars holds the current Iraqi government and the occupation forces responsible for any injustice against Iraqi people," said the group, which is believed to have links to the Sunni Arab-led insurgency fighting government and U.S.-led forces.
A significant portion of the Iraqi national police is believed to be aligned with militias, and U.S. officials have said efforts are under way to weed out corrupt security agents.
The office of Prime Minister Nouri al-Maliki said the Sunni group's statement was wrong.
"What has been written in the statement of the Association of Muslim Scholars is absolutely incorrect and it could provoke sedition," al-Maliki's office said. "We hold the association responsible for anything that could happen as a result of this."
