US President Joe Biden says US troops may stay in Afghanistan beyond his planned 31 August withdrawal date to help evacuate Americans, writes BBC.

There have been chaotic scenes at Kabul Airport as foreign powers seek to get their citizens home.

President Biden again defended his handling of Afghanistan, where the Taliban have capitalised on the US pulling out to sweep to power.

“The idea that somehow there"s a way to have gotten out without chaos ensuing, I don"t know how that happens”, - he said.

Mr Biden had wanted US forces out by the end of this month, but thousands of US citizens are stranded in the country.
