In the aftermath of the suspected suicide bombing at Domodedovo airport which killed over 35 people and injured many others - a grizzly image has appeared on Russian NTV television showing a photograph of what seems to be the severed head of the suspected suicide bomber.
It's said to be of a "man aged 30 to 35 and of North Caucasus or Arab appearance" according to the Moscow Times.
Curiously, there's a big difference between the two, as there are big physical differences even among Arabs, for example between a Lebanese and a Yemeni or a Palestinian and a Northern Sudanese.
