Explosions have been heard at the Azovstal steel plant in Mariupol where around 200 civilians remain trapped.
Footage from the scene shows thick plumes of smoke rising into the air as loud explosions are heard in the background.
The plant is the last pocket of Ukraine resistance in the southern port city, which is now almost entirely occupied by Russian forces.
Hundreds of civilians are thought to be holed up in bomb shelters beneath the industrial complex alongside soldiers, marines and medics.
