Ahram on Tensions between Egyptian Army and Hamas and MB

Here's an interesting piece at Ahram Online on growing tensions between the Egyptian Army on the one hand and both he Muslim Brotherhood and Hamas on the other, involving recent allegations of Palestinians found at Cairo airport with maps of Egypt, of alleged Hamas involvement in the killing of 16 Egyptian border troops at Rafah last August, and other issues relating to Sinai security. While a lot of it seems based on rumor, it is yet another side that the Army is not entirely happy. Given the close links between Hamas and the Muslim Brotherhood (the Gaza MB, which became Hamas, was created by the Egyptian MB years ago), it seems worth noting.
