A new image of a Yeti - or Bigfoot - lurking behind trees is the 'clearest evidence' so far of the creature's existence.

So claims leading Yeti proponent Igor Burtsev, Director of the International Centre of Hominology in Moscow. It comes as Dr Burtsev is fending off claims from a UK newspaper that samples of 'Yeti hair' which he provided have turned out under DNA analysis at Oxford University to be horse, racoon and American Black Bear.
While disputing the results of the test, he has released footage which he claims shows a fleeting two second glimpse of shadowy object moving behind snow-covered trees some 30km from the coal mining city Leninsk-Kuznetskiy in Kemerovo region.
'Three boys made a video of the Yeti', he said.
'They were in the area near the city of Leninsk-Kuznetskiy, some 30 km away. They were walking about and noticed a chain of huge tracks in the snow.
'They got very inquisitive about the tracks and followed the trail, filming them on the mobile phone camera.
'They walking for a bit and got closer to the bushes - where suddenly they saw a Yeti, some 50 metres away from them.
'It noticed them as well, sharply moved, bent down, then to the left, and ran left. The boys, scared, ran in the opposite direction.'
One - Yevgeny Anisimov, 11, who is filming the 'creature' - is heard shouting: 'I am the nearest, I'm going to be eaten.'

Yevgeny was with friends Kirill Soldatov, 12, and Alexander Pereverin, 11, who also ran away. The 'incident' was in late January, said Burtsev, who did not elaborate on how he received the footage.
'I was sent it from Kemerovo, and the first thing I did was to check it with the experts,' he said. 'They said there is no doubt that the video is genuine. I have sent a copy of the video to Kemerovo region governor Aman Tuleyev.'
Burtsev insisted: 'It is a first time in Russian modern history that someone manages to film the Yeti so clearly.'
He added: 'I don't doubt it was a Yeti. It stood in a typical pose with its back slightly bent, and its long arms down. It is a real, not falsified, video. Soon the experts will try to establish what sex the creature was. The tracks in the snow were very interesting: not only long but large.
'It looks like it first walked towards the village and then walked back in its own footprints. It fits what we know about Yetis... they walk without a swagger.'
The footage shows tracks in the snow, which are apparently close together. Previously, Burtsev has stressed how Yeti tracks are normally far apart - by a metre at least.
The sighting - the latest of many claimed by Burtsev in the Kemerovo region of Siberia - came soon after British newspaper The Sun highlighted the results of DNA tests on hair from the region conducted by Professor Bryan Sykes of Oxford's Wolfson Institute, one of the UK's leading geneticists.
The newspaper headlined its story: 'Bigfoot: It's Yogi Not Yeti' after one of three samples which were supplied by Burtsev turned out to be an American Black Bear, a species not found in Russia. Another was horse hair. And a third was a racoon, not native to Russia.
'The hairs did not come from a Yeti,' said Professor Sykes.
'The American black bear result was highly unusual. An explanation could be an animal escaped from a circus, zoo or private collection, but it is extraordinary'.
However, the three samples of hair when provided to the newspaper, which gave them for analysis to the prefessor, were said to comprise hair from Azass cave, in the Tashtagol district of Kemerovo region, another sample of hair found by the Kungushev family elsewhere in Tashtagol district, and a sample from Michigan in the USA collected by a local woman who claims to feed local Yeti.
So it was not surprising that an American animal might be shown by the DNA test. It is understood the sample that was found in the cave was horse hair.
The 2011 find of hair in the cave - during an international expedition in search of the Yeti which involved US supporters of the existence of Bigfoot - led to worldwide headlines.

Still the DNA result was clearly a blow for Russian Yeti hunters who remain adamant that the creature exists.
'I confirm that indeed The Sun has asked us for the samples of the hair, and we passed them on,' said Burtsev.
'But then it was passed via a third party, so I don't know what happened there. Could it be that Sykes didn't actually test them but only made a suggestion based on the visual analyses on the hair? Or perhaps the hair was contaminated?
'There is no way I would take The Sun's publication seriously, absolutely not. We cannot agree with the results of the test either.'
He joked: 'Perhaps they shaved one of the beefeaters hats? It would fit as it would be the right kind of bear's hair.'
He attacked claims that the Yetis do not exist in Kemerovo.
'We have a gigantic number of other evidence except for the hair confirming not only the Yeti's existence, but the fact that they live in Kemerovo,' he said.
'And the most recent evidence came after the story in The Sun from these three boys who made a video of the Yeti'.
