By Alessandra Prentice SIMFEROPOL, Ukraine (Reuters) – Thousands of pro-Russia separatists tussled with supporters of Ukraine’s new leaders in Crimea on Wednesday as tempers boiled over the future of the region following the upheaval that swept away President Viktor Yanukovich. About 2,000 people, many of them ethnic Tatars who are the indigenous group on the Black Sea peninsula, converged on the parliament building to support the ‘Euro-Maidan’ movement which overturned Yanukovich in Kiev after three months of protests. They were met by a similar number of pro-Russia demonstrators who bellowed loyalty to Moscow and denounced the “bandits” who had seized power in the Ukrainian capital. Crimea was transferred from Russia to Ukraine in 1954 in the Soviet-era by then Soviet leader Nikita Khrushchev.
