Moscow says truck explosion destroys part of Russia-Crimea bridge
A blast on the strategic road-and-rail bridge linking Russia and the Crimea peninsula on Saturday brought down sections of road taking traffic in one direction.
The 19-km (12-mile) bridge linking Crimea to Russia's transport network represents a crucial supply route for the Russian forces who have taken control of most of southern Ukraine's Kherson region.
The Russian National Anti-Terrorism Committee said on social media that the blast occurred at 6:07am in a freight truck, and caused seven fuel tanker wagons to catch fire on a train heading for the peninsula.
It said two sections of road bridge had partially collapsed, but that the arch spanning the Kerch Strait, the waterway through which ships travel between the Black Sea and Azov Sea, was not damaged.
Sergei Aksyonov, the Russian governor of Crimea, said on social media that the road bridge was still intact in one direction, although traffic was suspended while the damage was assessed.
Images showed thick smoke pouring from part of the bridge.
Later, the Emergency Ministry said the fire had been extinguished, the Russian news agency Interfax reported.
A Ukrainian presidential adviser posted a message on Twitter saying the incident was just "the beginning" but stopped short of saying Ukrainian forces were responsible for the blast.
"Everything illegal must be destroyed, everything that is stolen must be returned to Ukraine, everything occupied by Russia must be expelled," Mykhailo Podolyak wrote.
Putin has instructed the government to create a state commission to investigate the incident, TASS news agency reported, citing Kremlin spokesman Dmitry Peskov.
Interfax quoted the chairman of the Crimean republic's State Council, Vladimir Konstantinov, as saying that "Ukrainian vandals managed to reach for the Crimean bridge with their bloody hands".
"They now have something to be proud of," he said. "In their 23 years of economic activity they failed to build anything worthy of attention in Crimea, but (now) they have managed to damage the roadway of the Russian bridge."
Konstantinov said the damage was "not of a severe nature" and would be quickly repaired.
