MOSCOW (AP) — Four men accused of staging the Russia concert hall attack that killed more than 130 people have appeared before a Moscow court showing signs of severe beatings. All four were charged with terrorism. One appeared to be barely conscious during Sunday’s hearing. Court statements say two of the suspects accepted their guilt in the assault, though the men’s condition raises questions about whether they were speaking freely. The authorities formally charged the men with committing a group terrorist attack resulting in deaths. The offense carries a maximum sentence of life imprisonment. Moscow’s Basmanny District Court ordered that the men, all of whom are citizens of Tajikistan, be held in pre-trial custody until May 22.
