A large fire on the only crossing between the occupied Crimean peninsula and Russia was caused by a lorry explosion.
A blast on the road section led to oil tankers on the rail section catching fire, before the road collapsed.
Russia’s National Anti-Terrorism Committee (NAC) said: “At 06:07 Moscow time today [03:07 GMT], an explosion was set off at a cargo vehicle on the motorway part of the Crimean bridge on the side of the Taman peninsula, which set fire to seven fuel tanks of a train that was en route to the Crimean peninsula.
“Two motorway sections of the bridge partially collapsed,” it added.
Russian President Vladimir Putin has been briefed about the “emergency” on the bridge and has ordered a government inquiry, Kremlin spokesman Dmitry Peskov said, in comments quoted by Interfax news agency.
The sales of tickets for trains to and from Crimea were suspended following an incident on the Crimean Bridge and all trains were canceled, the Russian Railways company said in a statement.
"All trains to and from Crimea, which were expected to depart in the near future, have been temporarily canceled. Ticket sales have been suspended. Passengers can return tickets for the delayed or canceled trains without additional fees," the statement reads.
