Dozens dead and 17 feared trapped after explosion at coal mine in Iran

The explosion at the coal mine in Tabas in eastern Iran on Saturday night killed at least 52 workers and injured 17 others, state media said, making it one of the worst mining disasters in the country's history.

Video posted online showed weeping miners stood alongside mine cars that brought up the bodies of their colleagues, all covered in coal dust.

Around 70 people had been working at the time of the blast. State television later said that 17 were believed to be trapped at a depth of 200 metres down a 700-metre tunnel. However, figures kept changing throughout Sunday regarding the disaster in the rural area with some reports suggesting the death toll was higher.

Authorities blamed the blast on a leak of methane gas. Such gases are common in mining, though modern safety measures call for ventilation and other measures to protect workers.

It wasn't immediately clear what safety procedures were in place at the privately owned Mandanjoo Co., which operated the Tabas Parvadeh 5 mine.

Iran’s new reformist President Masoud Pezeshkian, preparing to travel to New York for the U.N. General Assembly, said that he ordered all efforts be made to rescue those trapped and aid their families. He also said an investigation into the explosion had begun.

“I spoke with the ministers of health, interior and security and ordered that the issues of the families of the victims and the injured be quickly resolved,” Pezeshkian said, according to a statement from his office. “I also requested to take measures to prevent the recurrence of such incidents by improving work standards in the country’s
