Iraq's government spokesman says the U.S. offers of changes in the draft security agreement were "not enough."

Ali al-Dabbagh also is asking Washington to offer new amendments if it wants the pact to win parliamentary approval.

Al-Dabbagh's comments on Monday were the first public statements by the Iraqis to last week's U.S. response to an Iraqi request for changes in the draft agreement.

The pact would keep U.S. troops in Iraq until 2012 and give Iraq a greater role in the management of the U.S. mission.

He says the "American answer is not enough" for the government to accept it in its current form.

Al-Dabbagh says the government is inviting the U.S. "to give answers that are suitable to the Iraqis."
