Russian bombers fly around Europe to strike Syria in 8,000 mile show of strength - Telegraph
Approximating their route on Google Earth suggests that they would have flown 6000ish miles just getting to Syria, which is a pretty long way. They apparently returned via Iran and the Caspian Sea, so the minimum distance flown is 7400ish miles.
Getting close to Blackbuck distances...
