Afghanistan: Hamid Karzai says US cutting supplies to put pressure on security pact --- The president of Afghanistan, Hamid Karzai, and his national security council have accused the United States of cutting military supplies, including fuel, to put pressure on the country to sign a security pact, a statement from Karzai's palace said on Sunday. The US embassy in Kabul denied that supplies had been cut. -- Tensions between Karzai and his American backers have escalated since the Afghan president said last week that he would not sign a crucial bilateral security deal until a suite of new requirements had been met – despite the deal already being agreed upon. -- On Sunday Dianne Feinstein, the chair of the US Senate intelligence committee, had strong words for Afghanistan's president over his refusal to sign the deal. Feinstein, appearing on CNN's State of the Union talkshow, said she thinks Hamid Karzai "is such a cipher" and added that Karzai was "so much the victim of what thought occurs to him right at the moment based on some anger that he feels about something that may not even be related".
