[Photo] A man filmed four Ufos hovering over the Houses of Parliament

London man Derek Burden recently used his mobile phone to film four Ufos hovering over the Houses of Parliament, British media reported. He was working on the 16th floor of Covent Garden in West London at 8.30am when he took random pictures with his mobile phone. It was only when he and his wife Sarah looked at the photos a few days later that they noticed the strange shapes in the space, which was covered by thick clouds.
