Explosions and Gunfire Rock South Sudan

Renewed fighting has broken out in South Sudan between forces loyal to the president and vice-president. We get the latest from the capital Juba and the wider context from our Africa editor Mary Harper. Also in the programme: We speak to the Syrian migrant who filmed his journey to Europe, and the pilot of the Solar Impulse zero-fuel plane flying from Seville for Cairo.
