Allies of Putin are calling for a swift response after an explosion on a bridge.

Russian officials said a truck explosion caused the bridge to collapse.

Putin ordered the source of the explosion to be investigated, but some in Russia blamed the Ukrainians. The morning after the Russian president's 70th birthday, some Ukrainian officials suggested that they may have been behind the blast.

There is a road and rail link between Russia and the Ukrainian territory of Crimea. It serves as a key supply route for transporting essential goods like fuel and equipment to Russian forces who are struggling as they try to ward off more Ukrainian counteroffensives.

The opening of the bridge held personal significance to Putin, who oversaw it and drove a truck across it.
