A video posted to the internet supposedly shows the two suicide bombers behind last month's attack in Russia threatening the Sochi Olympics. The bombers said they were the first wave.
They said the next attacks could bring a "surprise" to the Olympics.
The bombers are now dead but it's still causing concern about security.
Analysts say it's an opportunity to get attention, the winter games begin in 17 days.
