large fire on the only crossing between the occupied Crimean peninsula and Russia was caused by a lorry explosion, Russian officials say.

A blast on the road section led to oil tankers on the rail section catching fire, before the road collapsed.

Crimea was annexed in 2014 by Russia, which now uses the bridge to move military equipment into Ukraine.

The official Twitter account of the Ukraine government responded to the fire by tweeting: "Sick burn."
