Ukraine's Explosive Actions Sever Railway Connections with Russia

Ukraine's security service has claimed responsibility for blowing up a rail connection deep inside Russia, targeting an important piece of infrastructure that the Russians sometimes use for military purposes. Successive explosions occurred on trains running through a tunnel and a bridge in Russia's far east. The extent of the damage is unverified, but reports suggest damage to fuel tanks and rail lines. Russia has initiated an inquiry into a "criminal case of terrorism" in response to the attacks.
