Defiant US president says he “stands squarely” behind withdrawal after 20 years in the country.
The Taliban is in control of Afghanistan after President Ashraf Ghani fled the country and conceded power to the armed group 20 years after it was deposed in a US-led military invasion.
The astonishingly quick collapse of the government, with the Taliban taking over the presidential palace on Sunday night, triggered fear and panic in the capital.
Thousands of people rushed to the airport trying to flee the country as they feared the Taliban’s hardline rule.
After police and other government forces gave up their posts in Kabul on Sunday, Taliban fighters took over checkpoints across the city and entered the presidential palace.
Taliban fighters with rifles slung over their shoulders also walked through the streets of the Green Zone, the formerly heavily fortified district that houses most embassies and international organisations.
