US National Security Adviser Rice meeting Afghanistan's Karzai after he rebuffs security deal

U.S. officials say National Security Adviser Susan Rice will meet Afghan President Hamid Karzai in Kabul just one day after he rebuffed American requests to sign a security pact by the end of the year

A spokesman for the U.S. Embassy and the White House said Monday's meeting was at Karzai's request. Rice was on a trip to visit U.S. troops for the Thanksgiving holidays.

Karzai on Sunday rejected a recommendation by an Afghan assembly of dignitaries that he quickly sign.

The U.S. administration insists the deal be finalized by the end of next month, warning that planning for a post-2014 military presence may be jeopardized if it is not approved.

Karzai's decision to defer its signature after April's elections cast doubt on the presence of American forces after 2014.
