BAGHDAD , Iraq ( CNN ) -- U.S. troops or contractors who commit `` major and premeditated murders '' in Iraq while off-duty and outside U.S. facilities would fall under Iraqi jurisdiction , according to a copy of a draft U.S.-Iraq agreement obtained by CNN . Shiite demonstrators protest a proposed U.S.-Iraqi security pact Saturday in Baghdad . All other crimes -- including murders committed inside U.S. facilities or by on-duty forces -- would fall under American jurisdiction , according to the draft , which would govern U.S. troops ' presence in Iraq . The issue of whether U.S. troops would remain immune from Iraqi prosecution has been a sticky one for negotiators crafting the Status of Forces Agreement draft , which Iraqi lawmakers are reviewing . The United States had preferred its troops and contractors retain immunity . The draft also calls for U.S. combat troops to be out of Iraqi cities by July 30 , 2009 , and out of the country entirely by December 31 , 2011 . The agreement allows for an earlier withdrawal or an extension of the U.S. forces ' stay in Iraq , by agreement of both parties . It also allows the Iraqi government to `` request from the United States government to leave certain forces for training and for support purposes for the Iraqi forces . '' The governments have been trying to get a deal before December 31 , when a U.N. mandate authorizing the U.S. troop presence in Iraq expires . Iraq 's ruling Shiite parliamentary bloc said Sunday it needs more time before it can approve the draft . The United Iraqi Alliance bloc found several `` points '' in the draft that `` need more time for discussion , dialogue and amendments [ to ] some of its articles , '' according to the Supreme Islamic Council of Iraq , the most powerful party in the bloc . It was unclear what specific `` points '' the parliamentary bloc was questioning . Thousands of people marched in central Baghdad on Saturday to protest the draft U.S.-Iraqi security agreement . The political party of Iraqi cleric Muqtada al-Sadr called for the rally . Watch marchers protest the agreement » . Baghdad had sought the power to arrest and try Americans accused of crimes that are not related to official military operations , plus jurisdiction over troops and contractors who commit grave mistakes in the course of their duties . The United Iraqi Alliance on Sunday night discussed the draft , which was presented by Iraqi Prime Minister Nuri al-Maliki , whose Dawa Party is also a member of the ruling bloc . Iraq 's Political Council for National Security needs to approve the draft before al-Maliki sends it to his cabinet . The council includes the leaders of various political blocs -- including the United Iraqi Alliance -- as well as Iraq 's president , prime minister , vice presidents , and speaker of parliament . If the cabinet passes the draft by a two-thirds majority , al-Maliki will submit it to the Iraqi parliament for approval . A senior Bush administration official said last week that the U.S. is examining `` contingencies '' in case the Iraqi government is unable to sell the status-of-forces deal to the country 's various factions . If Iraq does not approve the deal , fallback options include `` a new U.N. Security Council resolution legally authorizing the extension of the U.S. footprint '' or an `` informal agreement between the United States and the Iraqis , '' the official told CNN last week . The official spoke on condition of anonymity because of the sensitivity of the discussions . Other points covered in the draft agreement include Iraqi ownership of `` all the buildings , facilities and structures that can not be transported and are connected to the ground '' and used by American forces . Such facilities will be returned to Iraq when the agreement expires , it says . Further , the agreement requires the United States to immediately return to Iraq any `` historic or cultural site '' it discovers at facilities it is using . The agreement allows the United States to use whatever defensive systems it deems necessary in areas under its control . Yet it bars `` systems of weapons of mass destruction ( chemical , nuclear , radiological , biological weapons and waste related to these weapons ) . '' The United States is to transfer control of Iraqi airspace to Iraq when the agreement goes into effect , although Iraq can ask for assistance for airspace control and surveillance . The agreement also covers environmental issues ; the comings and goings of troops in and out of Iraq ; movement of vehicles , planes and ships ; and the movement of equipment in and out of Iraq . Secretary of State Condoleezza Rice is lobbying Iraqi leaders to pass the draft text of the agreement by the end of the year , State Department spokesman Sean McCormack said last week .
