(YOUTUBE) - A claim of responsibility that emerged Sunday for last month's back-to-back bombings in the Russian city of Volgograd also threatens "a present" for visitors to the upcoming Winter Olympic Games in Sochi. In a video posted on a well-known Jihadi forum website Sunday, two young men believed to have been suicide bombers speak of the Volgograd attacks and also make an ominous promise.
"We've prepared a present for you and all tourists who'll come over. If you will hold the Olympics, you'll get a present from us for the Muslim blood that's been spilled," the video says.In the video, the men are dressed in black and standing in front of a black banner with religious verse that is typically associated with al Qaeda-linked extremists.
Last month's attacks in Volgograd, a major transit hub about 650 kilometers (400 miles) away from Sochi, sparked concerns over security as the Olympics approach. The explosions targeted a train station and a trolley bus and claimed the lives of more than 30 people.
The fresh claim of responsibility came on the same day that Russian President Vladimir Putin pledged that visitors to Sochi for the Winter Olympics, due to start in less than three weeks, will be kept safe.
