The operator of the Turkish mine where 284 workers were killed this week in Turkey's worst ever mining disaster has said there was no negligence on the part of the company and that it still did not know the exact cause of the accident.
"We still do not know how the accident happened. There is no negligence of ours in this incident. We all worked heart and soul," said Akin Celik, the plant manager of the mine, run by Soma Holding.
