Ankara, Oct 17 : Five prosecutors were appointed to investigate an underground coal mine explosion that killed 41 workers in northern Turkey, the country's Justice Minister Bekir Bozdag said. "I would like to express clearly to the public that this incident will be investigated and clarified in all its aspects. No matter how many questions there are, they will all be answered," he added on Sunday. Eleven others were injured and hospitalised in the explosion, which occurred 300 metre below ground on Friday at the Amasra Hard Coal Enterprise in Amasra town, state and local officials said. If there is any negligence, fault, or deficiency, the law will do what is necessary, the Turkish Minister emphasized.
