Two rescue workers die in Karviná mine

Two rescue workers died in a mine in Karviná, Silesia on Sunday night. Investigators said the men, who were both aged 43, had probably been poisoned when collecting air samples in an underground space. The mine’s operator, OKD, said it did not want to speculate about the cause of death, but did rule out several other possibilities. The two deaths were the first fatalities recorded this year in Karviná, which last year registered five.
