Doku Umarov calls for Islamists to disrupt Sochi Winter Olympics The Chechen fighter called the Games - to be held near Russia's Black Sea resort of Sochi in February - "satanic dances on the bones of our ancestors." Mr Umarov, whose militants had earlier launched numerous suicide bombings in Moscow and other cities that resulted in scores of civilian casualties, announced a moratorium on terrorist strikes in early 2012. He said at the time that the ceasefire was introduced because Russians were rising up against the Kremlin in a series of street protests. But the 49-year-old militant declared in a video message posted online on Wednesday that the moratorium was being lifted because "unbelievers" in Moscow had treated it as a sign of weakness and "only increased their persecution of peaceful Muslims." A low intensity guerrilla conflict between several hundred militants and Russian security forces has flared in the North Caucasus for the last decade, after two full-scale wars in separatist Chechnya. Mr Umarov, who said his Caucasus Emirate coalition was part of a global jihad, claimed Russia's "barbaric actions" in the region had forced him to retaliate. Peaceful Circassian activists, mostly living outside Russia but with roots in the North Caucasus, have already been protesting that the Winter Games should not be held near Sochi, where many people of their nationality were killed by Russian tsarist troops in the 19th century. "We know that that they want to hold the Olympics on the bones of our ancestors, on the bones of many true Muslims who perished and were buried on our lands along the Black Sea," said Mr Umarov. As Mujahideen, we are obliged to prevent this using any methods that Allah permits us. The Sochi 2014 Organising Committee told news agencies that security would be a top priority at the Games.
