A video which some say proves the existence of Iceland's answer to the Loch Ness Monster has sparked fierce debate in the country.
The footage shows what looks like a creature swimming in the Jokulsa River. It is believed, by many, to be a legendary monster known as the Lagarfljot river worm.
The worm is the most well know monster in Icelandic folklore - sightings date back to 1345.
The video was shot on February 2 by local resident Hjortur Kjerulf and put onto the Icelandic broadcaster RUV's website later that day. It quickly became an internet sensation. The page was inundated with visits from all over the world wanting to view the alleged monster.
The creature is seen winding or twisting in the river below a farm and seems to be swimming into the stream.
According to RUV, the legend has it that the worm had first been a small heather worm that was put onto a golden ring. This was done so the gold would grow and the ring would become bigger. When the owner of the ring came to collect it some time later, he realised, to his great horror, that the worm had grown enormously but the ring had not. The owner threw the ring and the worm into Lagarfljot River where the worm continued to grow.
Some people believe the video merely shows a bit of fishing net. They say the net blew into the river and froze. Then when the ice cleared, the so-called worm started to slither around in the river.
