U.S. officials have called off scheduled talks with Pakistani and Afghan officials amid growing diplomatic tensions between the United States and Pakistan. The United States did not provide specific reasons for its postponement, though the imprisonment of a U.S. embassy official in Pakistan has strained U.S.-Pakistani ties. Raymond Allen Davis has admitted to killing two people he said threatened him while he was driving in Lahore last month. A third Pakistani was reportedly run over and killed by a U.S. consulate vehicle that arrived at the scene. The U.S. embassy claims Davis, a former Special Forces soldier, acted in self-defense and, as a diplomat, is entitled to immunity. Davis’s diplomatic status has been called into question. Pakistani media reports have suggested he is a CIA operative or private security contractor.
