With the world looking on in disbelief, the Taliban has swept to power in Afghanistan, sparking global calls for the extremist group to allow swathes of people who want to flee the country to safely do so.

Amid warnings of a potential humanitarian disaster, some Afghans tried to cling onto the wheels of a US Airforce plane at a chaotic Kabul Airport in a bid to flee the country, with three believed to have fallen to their deaths.
