Ramadi, hey? Either it is an old tape or they have good reason to hide their faces.

"Because of the campaign against al-Qaeda in Anbar, al-Qaeda and Zarqawi are said to "have begun fleeing Anbar province and Ramadi, its capital, to cities and mountain ranges near the Iranian border." Zarqawi has proven to be quite elusive, and the latest rumor of his capture has yet to pan out. He was last believed to be in the Hamrin region of north-central Iraq."
We know Zarqawi is connected to Ansar al Sunnah and Iran. I honestly don't know when this tape was filmed; but Zarqawi only just started fleeing there.
