John Kerry Arrives in Kabul on Unannounced Visit

NATO combat troops expected to leave Afghanistan by December 2014

US Secretary of State John Kerry has arrived on an unannounced visit to Kabul amid troubled negotiations with Afghanistan on US troops staying in the country after 2014.

President Hamid Karzai said this week that he was prepared to walk away from the Bilateral Security Agreement (BSA) talks if Afghanistan was not happy with its conditions.

But the United States has repeatedly pushed for the pact to be signed by the end of this month so that the US-led NATO military coalition can schedule its withdrawal of 87,000 combat troops by December 2014.
