Russian forces kill Islamic State-linked hostage takers at detention centre

State media said that some of the men had been convicted of terrorism offences and were accused of affiliation with the Islamic State militant group, which claimed responsibility for a deadly attack on a Moscow concert hall in March. The six hostage takers, one of whom wore a headband with the flag used by the Islamic State that bears an Arabic inscription, knocked out window bars and climbed down several floors by rope before taking the guards hostage with a knife and fire axe.
