The resurgent Taliban have taken more territory in Afghanistan in the last two months than at any time since they were ousted from power in 2001.
Over the last 20 years, the control map of Afghanistan has been an ever-changing canvas. Here, we look at the fluctuating picture of who controls which areas.
It appears the Taliban have been emboldened in recent weeks by the withdrawal of US troops – retaking many districts from government forces.
US troops and their Nato and regional allies forced the Taliban from power in November 2001. The group had been harbouring Osama Bin Laden and other al-Qaeda figures linked to the 11 September 2001 attacks in the US.
But despite a continued international presence in the region, billions of dollars of support and training for the Afghan government forces, the Taliban regrouped and gradually regained strength in more remote areas.
About 15 million people – half the population – were reported to be living in areas either controlled by the Taliban or where the Taliban were openly present and regularly mounted attacks against government forces.
