Footage has emerged of a huge "iceberg tsunami" off the coast of Greenland that threatened to swamp a tourist boat.

The incident happened at the Ilulissat Icefjord, a Unesco World Heritage Site.

The video shows the crumbling iceberg creaking and cracking before a huge shelf shears off creating the massive wave.

The BBC said the video was captured by Jens Moller, the nephew of the captain.
