Bomb orsak till tågolycka i Ryssland- Chechen separatister tros ligga bakom

Aftonbladet skriver: Svår tågolycka i Ryssland – flera döda

Engelska Guardian skriver lite mer informativt: Bomb suspected in Russia train crash

Där sägs det:

Russia has been beset by concerns over terrorism since the wars with Chechen separatists of the 1990s. Terrorists have repeatedly attacked Russian cities, although in recent years the number of attacks linked to Chechens has diminished. In its place violence from the republic of Ingushetia has mounted. The small, poor and turbulent area of the north Caucasus has been gripped by an intensifying Islamist insurgency.

Russian forces have also been targets of sporadic attacks in lawless Dagestan, where Islamist militants and organised criminals are blamed for bomb blasts and shootings.
