ANKARA (AA) - A bridge connecting Crimea to Russia caught fire early Saturday morning.

The cause of the fire at the Kerch bridge is unknown, according to reports on social media.

Footage and images, widely shared on social media, show that a road section collapsed and train carriages were burning on the bridge.

A huge explosion was heard before the massive fire broke out, according to eye-witnesses and video footages.

The Kerch Bridge -- a pair of parallel bridges, one road and one railroad -- is a key supply route for Russia which was built after Crimea's annexation in 2014.
