KABUL, Afghanistan — Afghanistan's president on Sunday refused to sign a security deal with the United States until next April's elections, ignoring a recommendation by an assembly of Afghan elders and leaders that he do so by the end of 2013. Hamid Karzai spoke after the 2,500-member national consultative council known as the loya jirga approved the deal and asked that the Bilateral Security Agreement be signed by year's end.The loya jirga has no legal weight and can only recommend to Karzai what he should do. He convened the council to solicit their advice on whether he should sign the agreement or not. Karzai argued Afghanistan needed more time to ensure that the United States was committed to peace in the country and stressed that the April 5 elections were a key date. He also hinted that if the agreement is signed now, he will lose the influence he needs to ensure that the elections are not the subject of manipulation. President Barak Obama's administration has said it wants a deal signed by the end of the year and warned that planning for a post-2014 military presence may be jeopardized if it is not approved by Karzai. — AP
