Western countries warn of a terrorist attack on Kabul airport in Afghanistan where thousands are gathered.

UK Armed Forces Minister James Heappey tells BBC the threat is "severe"

There are no details of the threat, thought to be from so-called Islamic State militants.

The warning comes as efforts to evacuate people seeking to flee the country enter their final phase.

So far, more than 80,000 people have been flown out - with more than 10,000 currently awaiting at Kabul airport.

Up to 1,500 Americans may still need evacuating from the airport, which is controlled by US troops.

Westerners and Afghans who worked for foreign missions want to leave after Taliban militants came back to power.

The US aims to complete the evacuation - and US troop pull-out - by a 31 August deadline agreed with the Taliban.

There are fears thousands of Afghans who wish to flee may be left behind.
