Iraq: US agrees to limited jurisdiction

? American troops could face trial before Iraqi courts for major crimes committed off base and when not on missions, under a draft security pact hammered out in months of tortuous negotiations, Iraqi officials familiar with the accord said Wednesday.

The draft also calls for U.S. troops to leave Iraqi cities by the end of June and withdraw from the country entirely by Dec. 31, 2011, unless the Baghdad government asks some of them to stay for training or security support, the officials said.

It would also give the Iraqis a greater role in U.S. military operations and full control of the Green Zone, the 3 1/2-square mile area of central Baghdad that includes the U.S. Embassy and major Iraqi government offices.
