Afghans baulk at U.S. push for operations after 2014 - spokesman

KABUL (Reuters) - A U.S. bid to run unilateral counter-terrorism operations in Afghanistan after 2014 is threatening to derail a security pact between the two countries, an Afghan spokesman said, underlining Afghanistan's tenuous ties with its main backer.

Most foreign combat troops are due to leave by the end of 2014, and the United States has been putting pressure on Afghanistan to finalise a bilateral security agreement by the end of this month.
