The death toll from a coal mine blast in the eastern Iranian province of South Khorasan has risen to 50 after one of the injured succumbed to his wounds, the official news agency IRNA reported on Wednesday.
Of the 16 workers injured in the mine explosion in Tabas County, two were in critical condition, with one declared dead after suffering brain death, IRNA quoted Mohammad-Ali Akhoundi, director general of the provincial crisis management headquarters, as saying.
The explosion occurred Saturday night in a mine tunnel about 540 km southeast of Tehran, triggered by a sudden rise in methane gas.
At the time, 65 workers were present in the mine, the report quoted Akhoundi as saying, revising the initial figure of 69 workers.
