The President of Afghanistan Hamid Karzai has been talking to the BBC about the US troop withdrawal from his country.

All international combat forces are due to leave by the end of 2014.

President Karzai has still not signed a follow-on security deal that would agree the framework for a handful to remain in an advisory role.

BBC World News' Yalda Hakim asked President Karzai if he was reluctant to sign because he is concerned about his own personal legacy.
