A Foreign Ministry spokesperson told The Jerusalem Post
that there has still been no official confirmation that there is in fact somebody in Egyptian custody, and if there is, that it is Ilan Grapel. It is important to note, he added, that the basics of the case are still being looked into. Reports in Israeli and Egyptian media on Sunday and Monday said that an American-Israeli citizen had been arrested by Egyptian authorities on suspicion of spying against Cairo for Israel.
Asked whether the American government is involved in efforts to release Grapel, the spokesperson said that if, as is reported, Grapel is in Egyptian custody and does hold US citizenship, he assumes that the Americans would be making their own efforts to have him released.
