2008 marks deadliest year for U.S. troops in Afghanistan.

Insurgents killed two U.S. soldiers in Afghanistan today, on the seventh anniversary of the 9/11 attacks. Today’s attack brings the total number of U.S. troops who have died in Afghanistan this year to 113, making it the “deadliest year for American forces since U.S. troops invaded the country in 2001 for sheltering Osama bin Laden.”
