Source?
Stuck in my mind, probably because I saw it after the theater attack in Moscow, and I learned that Chechnya was a problem back then. (In fact, Chechnya gave the Czars fits too...)
I think a cheap scifi movie about a Chechen (thinly disguised Chechen?) attacking a space station too, came out around the same time as the Moscow attack, also reinforcing "Chechnya".
