There have been several sources that have indicated that the refugees/illegal immigrants (I like your neutral terminology) have been killed on the Egyptian side of the border BY EGYPTIANS. The allegation is that the Egyptians are so embarrassed that fellow Muslims would flee their country, that they would rather shoot them than give Israel the chance to be the ones to give them sanctuary. The Jerusalem Post has several articles reporting on the murders of these Africans by Egyptian soldiers, as Ms. Fox's friend passed on to her. I would post links, but they are archived, so you'll need to pay to gain access to them. And while I do object to the use of an unidentified friend as a source- I hold greater objection to taking brunt personal shots anonymously.
