Afghan President Hamid Karzai is accusing the United States of coercive measures to pressure him into signing a long-term security pact. Karzai announced last week he wants to continue negotiations on a deal to maintain U.S. forces beyond 2014. On Sunday, Karzai said the U.S. has cut military supplies, including fuel, to his government in retaliation. The United States has denied the claim. Tensions escalated last week after a U.S. drone attack killed a child and injured two women in Helmand Province. The top U.S. commander in Afghanistan, General Joseph Dunford, called Karzai to apologize.
