Moscow concert hall attack suspects appear in court

STORY: The four men are accused of gunning down scores of people at a concert outside Moscow on Friday night in the deadliest attack inside Russia for two decades.

Moscow courts' official Telegram channel said the men, identified by Russian media as all being citizens of the ex-Soviet republic of Tajikistan living in Russia, would be remanded in pre-trial custody until May 22. Three of the four had pleaded guilty to all charges, it said.

After unverified and brutal videos of the suspects' interrogations circulated on social media, courtroom images published by Russian media showed one suspect was brought in on a wheelchair apparently missing an eye, another had a bandage where his right ear should be, another had a black eye and a ripped plastic bag around his neck, and a fourth suspect with a swollen face seemed disoriented and struggling to keep his eyes open.

Unverified footage posted to Russian Telegram channels appeared to show one of the suspects being tortured with electric shocks in detention. Reuters could not verify its authenticity.
