Ukraine is marking the 10th anniversary of the shooting of dozens of protesters in Kyiv during the Maidan Revolution, which toppled the country's Moscow-backed president Viktor Yanukovych and led to Russia's annexation of Crimea and a pro-Russian separatist movement in the east. FRANCE 24's Gulliver Cragg spoke with Denys Tarakhkotelik, a protest leader during the revolution who runs Yanukovych’s former estate as a park and museum, and activist Oleh Symoroz about how Ukraine is tackling corruption a decade after Maidan.
