Very fast UFO caught over Jerusalem, Israel

On September 22, 2015, a witness has caught a black UFO over Jerusalem, in Israel. He has published his photo on MUFON website (case number 77207).

Witness report:

While in Jerusalem late Sept 2015, we took lot's of Photos with one having unknown/seen object in picture. Picture taken seconds before has No object!
At first I thought it could be a Bird. However, other than an occasional Pigeon seen at and around Human food sources we saw Few birds flying Anywhere around the country. We have several hundred pictures and Only the ones near Humans have birds. We also seen other things of the same nature while there but this is the only picture with an object we didn't notice or possibly see with the Naked eye?
