“The forces of the Egyptian Fedayeen moved toward Israel, reached her capital, Tel Aviv, and caused heavy casualties to Israel along the border between Gaza and Tel Aviv.  Apparently this was necessary to make it clear to Israel that we are able to pay back and to move the battle into the very heat of Israel, and that the attack on Palestinians is considered an attack on Egypt itself.”
