Russia charged four men with acts of terrorism on Sunday, after at least 137 people were killed and 182 injured in the deadliest attack inside Russia for two decades. Islamic State (Isis) quickly claimed responsibility for the gun assault at the Crocus City Hall concert venue on Friday night and released video evidence.

Kyiv has strongly denied any involvement but is bracing for further blame. Putin is recently re-elected and hates to appear weak. As Russians queue up to lay flowers for the dead, it’s easier for him to blame Ukraine than admit to other threats that his mighty security forces missed.
