Russian authorities said that an explosion involving a truck on Saturday caused a fire and destroyed a section of a bridge linking Russia and Crimea. The bridge is regarded as a key supply route for Russian troops in southern Ukraine.

The Crimean Bridge - also called Kerch Strait Bridge or Kerch Bridge - is a structure 19 kilometers (12 miles) in length that passes across the Kerch Strait and links southern Russia to the Crimean Peninsula. The Kerch Strait links the Black Sea and the Sea of Azov.
