Rescuers in Iceland are working by hand to cut through the remnants of a collapsed ice cave as they search for two tourists missing for more than 24 hours since a glacier caved in. One person died and another was severely injured. The search resumed early Monday. Video showed rescuers working inside two large craters surrounded by the sand-blackened ice of the glacier in the southeastern part of the island. Police said a group of 25 tourists from several countries were exploring an ice cave when it collapsed shortly before 3 p.m. Sunday. Four people were struck by falling ice, with one dying at the scene and another flown to a hospital in Reykjavik.
