Russia has charged four men it says attacked a Moscow concert hall and killed at least 137 people.
Three were marched blindfolded into a Moscow court while the fourth was in a wheelchair. All were charged with committing an act of terrorism.
The Islamic State group, or IS, said it carried out Friday’s outrage at Crocus City Hall, and posted video.
Russian officials have claimed, without evidence, Ukrainian involvement. Kyiv says the claim is “absurd”.
The four were named as Dalerdzhon Mirzoyev, Saidakrami Murodali Rachabalizoda, Shamsidin Fariduni and Muhammadsobir Fayzov.
Video showed three of them being marched blindfolded by masked police into Basmanny district court in the Russian capital. All appeared injured.
Mirzoyev and Rachabalizoda’s eyes were blackened and the latter’s ear was heavily bandaged – reportedly from it being partially severed during his arrest.
Fariduni’s face was badly swollen and Fayzov was brought into court in a wheelchair and appeared to have an eye missing, according to the Reuters news agency.
