An eyewitness recalled seeing the Siberian city of Tyumen on lockdown as Russian special forces carried out an operation against armed affiliates of the self-proclaimed Islamic State (IS; formerly ISIS/ISIL) on Friday night.
"Around 10 pm, and I am living no so far from district Mayak, a big number of police cars passed by our house," he remembered. "I reacted at once, got into the car with my friend and headed toward the district."
The young man, a local resident, recalled seeing vehicles belonging to the Russian security services at a security cordon.
"There was for sure a shootout, sounds of a shootout, and that was maybe around 11 or 12 pm local time," he added.
Two terror suspects were killed during the operation, according to Russia's National Anti-terrorism Committee.
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.
