US officials say Iraqi Prime Minister Ibrahim Jaafari will meet President Bush at the White House next week, for talks on Iraq's constitution and progress made in the training of Iraqi security forces. The June 24th visit was announced just hours after Shi'ite negotiators in Iraq unveiled a compromise deal that will place 25 more Sunnis on the pan-Iraqi committee drafting a new constitution. Thursday's agreement breaks weeks of deadlock over the size and conditions of Sunni participation on the drafting committee. Under the deal, 15 Sunnis will join two others already on the committee. The remaining 10 Sunnis will serve as advisors. Both the United States and the European Union have backed calls for greater Sunni participation on the committee, which has four months to write a permanent constitution before a referendum set for October.
