In the UK, France, Germany and Jordan the number of Jews is small compared to the number of Moslems. Also Mossad would not be so blatant as to use the names of their own countrymen or be so amatuerish as to get recorded or involve numerous agents bumping into each other around Dubai. One thing we can be sure, since the UK is now talking to Israel about it,Mossad and MI5 will soon know the real identities of the killers. My guess is Egypt since he was smuggling weapons through their territory but he likely had lots of enemies. The signs of electricution on him shows he was tortured, a favorite Egyptian security forces pastime.
