Groups Hold Negotiations on Iraqi Charter

"BAGHDAD, Iraq (AP) - With U.S. mediation, Shiite Muslim and Kurdish officials negotiated with Sunni Arab leaders Sunday over possible last-minute additions to Iraq's proposed constitution, trying to win Sunni support ahead of next weekend's crucial referendum.

But the sides remained far apart over basic issues - including the federalism that Shiites and Kurds insist on, but that Sunnis fear will lead to the country's eventual break-up. And copies of the constitution were already being passed out to the public.

Though major attacks in the insurgent campaign to disrupt the referendum have waned in recent days, violence killed 13 Iraqis Sunday."

I find it hard to believe that they would consider any modifications at this point. It's bad enough that people will not now really know what they are voting on with so little time to study the draft.
