The Art Newspaper May 11, 2023: This week: the Sudan crisis. How are artists responding to another war in the East African country?

The photographer Ala Kheir joins us from Khartoum to tell us about the conflict in Sudan and how it is affecting him and other artists. We talk to Alyce Mahon, the co-curator of Sade: Freedom or Evil, a new exhibition at the Centre Cultura Contemporània de Barcelona (CCCB) in Barcelona about the 18th-century writer and libertine the Marquis de Sade and his artistic and literary influence, particularly in the 20th and 21st centuries.

And this episode’s Work of the Week is Gwen John’s La Chambre sur la Cour (1907-08), a painting of John herself in a Parisian interior. The picture is one of the highlights of an exhibition dedicated to John at the Pallant House Gallery in Chichester, UK.Ala Kheir on Instagram @ala.kheir.Sade: Freedom or Evil, Centre Cultura Contemporània de Barcelona, until 15 October.
