At least 35 miners have been dead and several dozens got injured in a coal mine explosion in the northeastern Iranian province of Golestan.
Rescue workers recovered 35 bodies from a coal mine in northern Iran after an explosion caused a tunnel to collapse.
The blast occurred at 12:45 p.m. local time (0815 GMT) in the Zemestan Yurt mine when workers were engaged to start a locomotive.
Ali Rabiei, minister of cooperatives, labor and social welfare confirmed the death of 35 miners in this fatal incident.
Iranian media said more than 30 of the injured were shifted to nearby hospitals.
The semi-official Fars news agency reported more than 50 workers were trapped in a two-kilometre-long tunnel filled with gas that is making rescue operation even much more tuff.
The mine has 500 workers and the explosion happened during a change of shift, Fars reported.
President Hassan Rouhani has sent Minister of Labour and Welfare to the affected mine site in order to ensure the proper rescue operation and the best treatment of the injured miners, state run news agency IRNA reported.
