CAIRO (Updated) – A senior Israeli defence official said on Sunday that Tel Aviv would not allow Egypt to deploy extra troops in Sinai, following the killing of five Egyptian security men by Israeli forces on Thursday, Al-Youm Al-Sabae reported. Amos Gilad added that in case of increasing more troops this will demolish Egypt-Israel Peace treaty signed in 1979. Thousands of Egyptians have launched demonstrations nationwide and outside the Israeli embassy in Cairo, protesting the killing of Egyptian security men on the Egyptian-Israeli borders. protesters have called on the cabinet to expel Israeli charge d'affaires in protest. Gilad considered these demonstrations as an expression of opinion as long as they do not go out of context. In an interview with the Israeli TV, Gilad said Egyptian Army should keep balance, emphasising that Egypt has no intention to change the peace treaty by deploying extra troops without coordination with Israel. Gilad said the incident was unintentional as it happened by mistake, claiming that Israeli Army never opens fire at Egyptians. Meanwhile, Egypt's cabinet said on Sunday that an Israeli statement expressing regret for the border deaths of policemen was insufficient but stopped short of saying if it would recall its Tel Aviv envoy. "The Israeli statement was positive on the surface, but it was not in keeping with the magnitude of the incident and the state of Egyptian anger toward Israeli actions," the official Middle East News Agency (MENA) quoted a cabinet statement as saying. But the statement did not contain the protesters' anger outside the Israeli embassy. They celebrated when a man,identified as Ahmed Shahaat, climbed up to the embassy on a top floor of the building where the embassy is located, took down the Israeli flag and replaced it with an Egyptian one, according to the local media.
