4 men charged in Moscow attack as Russia marks a national day of mourning

MOSCOW — Four men accused of staging the Russia concert hall attack that killed more than 130 people appeared before a Moscow court Sunday showing signs of severe beatings as they faced formal terrorism charges. One appeared to be barely conscious during the hearing.

Moscow's Basmanny District Court formally charged Dalerdzhon Mirzoyev, 32; Saidakrami Rachabalizoda, 30; Shamsidin Fariduni, 25;
