U.S., Afghans agree most of pact, elders to make final decision --- (Reuters) - U.S. Secretary of State John Kerry and Afghan President Hamid Karzai have reached preliminary agreement on a bilateral security pact that now depends on the approval of Afghanistan's tribal leaders. --- The draft includes a U.S. demand to retain legal jurisdiction over its troops who stay on in Afghanistan, which would give them immunity from Afghan law. --- The United States is insisting it cannot agree to a deal unless it is granted the right to try in the United States its citizens who break the law in Afghanistan. - "We need to say that if the issue of jurisdiction cannot be resolved, then unfortunately there cannot be a bilateral security agreement," Kerry told a news conference. --- A senior U.S. administration official said the sides had agreed on language in the draft deal that covers the issue of immunity and "that can be put to his Loya Jirga for their consideration".
