A large number of rescuers and responders have taken part in the operation,
The conditions are very difficult on the ground,
Ice cave tours happen almost the whole year,
Four people got stuck under the ice, two people have already been rescued from the ice and are seriously injured,
The search is still on for the two people trapped in the ice cave,
Although we think we know the location of the two missing, it is hard to say what amount of ice is between them and the rescuers,
Conditions during the search are difficult and darkness is now upon us,
