London, Oct 22 : An astonishing video footage of a ''flying saucer'' spotted in Turkey is being considered the "most important images of a UFO ever filmed".

The shots were captured earlier this year by 42-year-old night guard Yalcin Yalman in a compound in Turkey.

Almost two-and-a-half hours of footage features a variety of objects ranging from incredible flying saucer-type ''craft'' to clustering orb-like lights hovering in the night sky.

Yalman and a number of residents claim that the UFOs were spotted over a four month period between May and September near the compound in Istanbul.

“I don’t know what these things are. We filmed them several times and they are totally unknown to us. I was very excited when I saw them and I want the world to know that UFOs do exist,” the Sun quoted him, as saying.

The footage was handed over to the Sirius UFO Space Science Research Centre in Turkey who interviewed witnesses and painstakingly combed through the footage frame by frame.

International UFO researcher Haktan Akdogan said: "In this amazing video footage, physical forms of UFOs and their metallic structures are clearly noticeable.

"What is more important is that in the close-up of some footages of the objects, entities in them can be distinctly made out."

"We have spoken with all of the witnesses and had detailed analysis conducted on all two-and-a-half hours of footage.

"After conducting all of the analysis we came to the conclusion that this video footage is 100 per cent genuine.

"The objects filmed are structured objects and are not the result of misidentification or natural phenomena, aircraft or astronomical objects.

"They are not the results either of any kind of computer animation. Now is it a time for world governments to acknowledge the reality of UFOs.

"The images captured on film are expected to have a tremendous impact throughout the world and they are the most important UFO images ever caught on camera," Akdogan said.

The footage will be revealed at the UFO Data Magazine annual conference in Pontefract, West Yorks, on October 25. (ANI)
