Just in case you still, somehow, thought everything was on track. From the Wall Street Journal today:
Afghan officials said Sunday that a Taliban rocket landed near U.S. troops on patrol Saturday afternoon in eastern Wardak province. In response, they said, American forces—thinking they had come under attack from Afghan troops—fired on a nearby Afghan army post. The Afghan army returned fire, resulting in a fierce gunbattle that lasted about 10 minutes, officials said.
