London, January 24 : A UFO has been alleged to have attended the Inauguration Day of US President Barack Obama after a video of a dark object flying over the historic ceremony emerged.

The recording features CNN anchors talking about the 44th president's historic speech before turning to shoot a scene of Washington DC''s Capitol on January 20.

The footage later depicts a small dark object zooming past the Washington Monument as thousands braved the freezing weather to see America rewrite history with the swearing-in of their first African-American president.

The video, titled `Filmed by CNN News - UFO at Inauguration of President Barack Hussein Obama', was said to have become an online rage on the popular video-sharing website YouTube.

It has further prompted blogger discussions, with some dubbing it as a bird or a UFO.

"Personally, I think the little green men rocked up to join the rest of the world in wishing Obama well," the Sun quoted a blogger as saying. (ANI)
