It's a year since the protests in Ukraine's Maidan Square - protests that led to the fall of the pro-Russian government. Russian-born Andrey Kurkov has published his diary of the time. He's one of the country's most famous authors and supported the uprising. But, although he lives in Ukraine, he writes in Russian and because of that he's been rejected by some as a Ukrainian writer and accused of being a traitor by Russians. Sarah Montague asks him what role do language and culture play in war? And was the uprising worth it?(Photo: Andrey Kurkov. Credit: Volodymyr Shuvayev/AFP/Getty Images)
