Ukraine defence officials have taunted Russia after a key bridge connecting Crimea to mainland Russia was badly damaged in an explosion.
Ukraine have not claimed direct responsibility for the attack that destroyed a section of Kerch Bridge and led to an oil tanker on a passing train also catching fire.
Crimean officials confirmed road and rail travel across the bridge has been suspended, but said a ferry service has been set up. Initial reports from Russia suggested the explosion came from a vehicle.
