Friday marks the 10th anniversary of the war in Afghanistan.
The U.S. and its allies invaded Afghanistan Oct. 7, 2001 in response to the 9/11 terror attacks. Since then, Taliban leaders have been forced out of power and Osama Bin Laden was killed.
While progress has been made, the country's future is still up in the air. Insurgent violence remains a big problem and there are questions about the stability of the Afghan government. More than 2,700 U.S. and coalition troops have died in the war during the past decade.
President Obama has said that U.S. combat operations in Afghanistan will end by 2014.
