SIMFEROPOL, UKRAINE - MARCH 07: Muslim men, mostly Crimean Tatars, arrive for Friday midday prayers at the Kebir-Dzhami Mosque, which is the city's oldest, on March 7, 2014 in Simferopol, Ukraine. Crimean Tatars, hundreds of thousands of whom Stalin deported in the 1950s, make up between 15%-20% of Crimea's population and have historically been suspicious of Russian rule. The pro-Russian Crimean Parliament voted yesterday to secede from Ukraine, join Russia and hold a referendum on the issue on March 16. The Crimean population is majority Russian, a large number of whom are enthusiastically supporting annexation to Russia. (Photo by Sean Gallup/Getty Images) ( 477099187 )
