Russia's 'grey zone' war

Grigor Atanesian from BBC Russian joins us to discuss the theories around 'grey zone' warfare techniques and if, why, and how Russia is deploying them against the UK. Plus, BBC Korean's Yuna Ku explains how companies and celebrities are striving to appear politically neutral before the upcoming South Korean elections; how the Grand Mosque in Mecca has been expanded over the years to accommodate large numbers of pilgrims, with Reem Alsheikh from BBC Arabic; and the story behind a 'lost' masterpiece that recently sold for $1.3m, with Merve Kara-Kaşka from BBC Turkish.
