Afghanistan conflict 10 years on
More than 130,000 international troops are still in Afghanistan, 10 years after the start of the US-led invasion of the country.
Operation Enduring Freedom was aimed at tracking down Osama Bin Laden in the aftermath of the 9/11 terrorist attacks, and overthrowing the Taliban rulers who were sheltering him.
But while removing the Taliban took just weeks, former coalition commander General Stanley McChrystal has said the US and its allies still lack the knowledge to end the conflict successfully.
Paul Wood reports from Kabul.
