A giant wave resulting from ice that melted and dropped from a glacier swept five Danish tourists into the icy Kangerluarsuk Fjord on Greenland's west coast Sunday, killing two, reports KNR radio.

Uummannaq assistant police chief Carl Borup said that the tragedy occurred while the group of 15 tourists from the boat 'Kisak' stood on a plateau at the glacier to take pictures.

'Witnesses said that there was suddenly a loud sound like a helicopter and a huge wave came pouring in on them,' said Borup.

Five tourists were pulled into the water, three of whom were rescued by emergency teams. The two men killed were 70 and 73 years old and both from the Copenhagen area. The 73-year-old man's body was found immediately after the wave hit, but the 70-year-old was not found until later that evening.
