It's estimated that half-a-million people have been living in Zamzam - Sudan's largest refugee camp for people trying to escape the chaos of the country’s civil war. Now, tens of thousands are said to have fled the site after continued attacks from the Rapid Support Forces paramilitary. Ahead of a London-held conference that will discuss a potential ceasefire, we speak to a former UN envoy to Sudan.

Also in the programme: US President Donald Trump, alongside the leader of El Salvador, defends the American deportation of Venezuelans accused of gang violence to Salvadoran prisons; and an all-female group of celebrities, including pop star Katy Perry, head to space.
