A Russian landing ship docked in a Ukrainian city under enemy rule has caught fire amid suggestions of an "explosion" heard nearby.
Thick plumes of black smoke were pictured billowing into the air by shocked locals who shared the images on social media.
They showed a Russian ship, the alligator-class Orsk, ablaze with flames visible on the deck of the vessel. Some nearby have suggested another vessel has sank, although it has not been confirmed.
