US fears risk of Islamic State attack at Kabul airport

A security alert warned US citizens of possible “security threats outside the gates”. US defence officials say they are monitoring developments and considering alternative routes.

Also in the programme: a major summit on the future of Crimea.

Joining Anna Holligan to discuss these and other issues are Alex von Tunzelmann, a British historian, film and TV scriptwriter and Nelufar Hedayat, an British-Afghan journalist, documentary maker and podcaster.
