As many as five Afghan civilians have been killed and another eighteen wounded in a US attack in Afghanistan. Witnesses say US forces opened fire on a passenger bus near the Afghan city of Kandahar earlier today. The bus driver and a passenger told the New York Times a US convoy opened fire just as the bus began pulling over to the side of the road to allow another military convoy to pass. The bus was said to be full of civilian passengers when US troops opened fire. All of the windows on one side of the bus were shot out. Some of the wounded were left in critical condition, and the death toll could rise.
