Five mine workers have been injured in an explosion in a granite mine in the Iranian city of Ardakan.
Two miners were severely injured in the tragedy on Wednesday morning, according to a report by the state-run ISNA news agency.
An official at Iran's Lorestan University of Medical Science said in June that one miner dies every 16 days in Iran.
There are a total of 7,000 mines in the regime, of which around 5,600 mines are currently operating.
Iran holds three percent of the world's mineral reserves, making it the most mineral-rich nation in the Middle East and the third richest in Asia, with exports to 159 countries.
