RIP, very sad news
I'm quite sure our friend "thepharoah" will explain it much better but let me tell you that's because Arabic countries mostly don't follow the western naming system.(given name + surname) their names are usually consisted of 3-4 parts or more, sometimes they refer to the person wtih 1st part, 2nd part and 3rd part, sometimes the the part, the only consistent thing is the 1st part which is the given name. (the 2nd part is the father name)
for example, Egypt wrestling legend is worldwide known as Karam Gaber but I also read some Egyptian media know him as Karam Ibrahim.
