A Taliban suicide car bomber struck a NATO convoy in the Afghan capital Tuesday, killing six troops - five Americans and one Canadian, officials said. Twelve Afghan civilians also died, many of them on a public bus in rush-hour traffic. Escalating violence in Afghanistan is now the worst since the early months of the nearly 9-year-old war, killing 1,074 civilians so far this year as international forces struggle to establish security, an Afghan rights group said Monday, July 12, 2010.
