Russian Prime Minister Vladimir Putin meets survivors and relatives of victims of last weekend’s Siberian coal mine disaster.
He ordered a detailed investigation into the causes of the accident and says lessons must be learnt to avoid a repeat of such tragedies in the accident-prone industry.
Safety has been brought into question in many of Russia’s mines, and there have been repeated calls for standards to be tightened.
19 rescuers who entered the network of tunnels after the initial explosion were among more than 40 people known to have been killed after a suspected build up of methane gas caused two blasts just hours apart.
Fears of flooding have complicated efforts to try to free 46 miners still missing in the Raspadskaya pit in Western Siberia, located 3,000 kilometers east of Moscow.
350 miners were underground when the accident occurred, although most managed to escape.
