In 2001 an international coalition led by the USA invaded Afghanistan to destroy terrorist organisation Al-Qaeda when the Taliban refused to hand over Osama bin Laden. British forces went in alongside US troops. At the height of the conflict there were more than 130,000 NATO troops on the ground. By July 2021, nearly all NATO countries had fully withdrawn.
But, after 20 years of conflict, the Taliban again claim to be in control of Afghanistan.
In this video, we look at how the war in Afghanistan began, what Britain’s role was, and why the war lasted for 20 years.
