Rebel leader urges fighters to derail Sochi Olympics

Says they must ‘prevent’ Games slated for 2014

MOSCOW — A leading Chechen rebel on Wednesday called on Islamist militants in Russia’s North Caucasus to disrupt the upcoming Olympics in Sochi, reversing his previous appeal not to target civilians in the region.

Sochi is hosting the Winter Games in February, a pet project for President Vladimir Putin. The overall bill for the Games stands at $51 billion, making them by far the most expensive Olympics in history.

Doku Umarov, a Chechen rebel leader, urged his fighters to ‘‘do their utmost to derail’’ the Games, which he described as ‘‘satanic dances on the bones of our ancestors.’’

‘‘We have the obligation to use all means to prevent this,’’ he said in a video posted on a rebel website Wednesday.

Last year Umarov urged his fighters to avoid hitting civilian targets because Russians in Moscow were taking to the streets to protest against Putin.

Security experts have said the Islamic insurgency raging across the North Caucasus mountains that tower over Sochi is a daunting threat to the Games — although rebels have not attacked Sochi so far.

Dagestan, which lies about 300 miles east of Sochi, has become the center of the insurgency that spread across the North Caucasus region after two separatist wars in the 1990s in neighboring Chechnya. Rebels seeking to create an Islamic state have targeted police and other officials in near-daily shootings and bombings.

Tamerlan Tsarnaev, the elder of the two ethnic Chechen brothers who are accused of staging the Boston Marathon bombings, spent six months last year in Dagestan.

Jean-Claude Killy, head of the IOC coordination commission for Sochi, said such threats are to be expected.

‘‘We get threats before every Olympics,’’ he said. ‘‘This cannot be taken lightly. I think the Russians are well equipped to face the challenge.’’

The Sochi 2014 Organizing Committee said ensuring security at the Games is ‘‘the responsibility of the state’’ and will be its priority. ‘‘We are confident that the Games will be safe and comfortable for all as guaranteed by the Russian state,’’ the committee said.

Russia’s National Anti-Terrorism Committee said it is working to eliminate threats at all international sporting events in the country.

Press officers for the Interior Ministry in Russia’s southern district declined to comment.

An officer of the Interior Ministry’s special task force in the North Caucasus, who asked not to be identified because he was not allowed to comment publicly, said Umarov’s statement could prompt Russians to step up their efforts to comb the mountainous areas where Umarov could be hiding.

The United States declared Umarov’s group a terrorist organization in 2011 and offered up to $5 million for information leading to his capture.

Umarov’s group is blamed for bombing a Moscow airport in January 2011, two subway stations in 2010, and a Russian train in 2009.
