The danger of further explosions in a Russian coal mine has forced authorities to call off the rescue effort to find 24 missing workers.
A methane gas blast last weekend ripped through the mine near the Siberian city of Mezhdurechensk, killing at least 66 men.
Emergencies Ministry official Pavel Plat said rescuers had already done their job “outside the acceptable limits of risk” and they “could not be left to work in such a complicated situation”.
Authorities say search teams will go back into the mine in a week’s time if the conditions are right.
A fire is still burning in the mine and methane gas levels are very high and potentially explosive.
This latest mining disaster is the worst in Russia since 2007, when 110 workers died in the Kemerovo region.
