A video has emerged showing a major oil rig fire which has reportedly killed more than 30 people.

Another 42 people had to be rescued from the fire, on the Azeri platform in the Caspian Sea, off the coast of Azerbaijan.

The blaze broke out last night and a search and rescue operation has been ongoing in the hours since.

However, the rescue operation has been hampered by stormy weather, with local news sources reporting waves of up to 36ft.
