approximately 6:40 local time in Kabul, approximately two rounds of indirect fire impacted the U.S. Embassy compound. All Americans are accounted for and no injuries were sustained, the embassy said in a statement Wednesday. The Embassy continues to investigate the attack. The embassy did not elaborate on what kind of rounds were fired, or where in the compound they landed. A claim of responsibility was posted on the Taliban's official website. The group said it fired missiles at the U.S. Embassy and the main base of NATO, which leads the military coalition known as the International Security Assistance Force. The incident comes at a pivotal time in U.S.-Afghan relations. The two countries are working on an important security pact. The deal will lay out the U.S. military presence in Afghanistan after 2014 when the NATO-led force of some 80,000 troops is scheduled to leave. This month, U.S. Defense Secretary Chuck Hagel was in Afghanistan and said the security pact will be agreed upon despite a failure so far to forge a deal.
