Azerbaijan’s state energy company says 30 oil workers are missing after a platform in the Caspian Sea caught fire following a storm.
Socar told the BBC that 63 workers had been on the Guneshli platform at the time of the incident and that 33 had been rescued.
The firm said the fire began after a storm on Friday evening damaged a gas line.
The storm has hampered efforts to control the fire and rescue workers.
Earlier, Mirvari Gakhramanly, of Azerbaijan’s Oil Workers’ Rights Protection Committee, told the BBC that at least 31 workers were missing and were presumed dead.
