Russia's National Anti-Terror Committee released drone footage on Saturday showing the burnt-out remains of a building where two suspected Islamic State (IS; formerly ISIS/ISIL) militants were killed the night before.
The raid targeted a suburban home in the western Siberian city of Tyumen.
Several areas of the city were cordoned off and armoured personnel carriers were brought in.
Officials said the militants were holed up in a private home as Russian special forces stormed the apartment and killed the terror suspects in return fire.
The Federal Security Service say the IS-linked militants were planning to carry out a terror attack in the local area.
No victims were reported among civilians during the operation.
