A single network of Islamic extremists who identify with al-Qaeda's ideology is responsible for most of the attacks on Israelis along the Egyptian border over the past year, Israeli intelligence now believes.
Though the network is based in Sinai, many of its members are Egyptians who don't live in Sinai.
Egyptian newspapers have reported that two of the three terrorists involved in last month's attack near Mount Harif, which killed Cpl. Netanel Yahalomi, were formerly students living in Egypt's Nile Delta region. One was identified with the Muslim Brotherhood, while his comrade had recently joined the Salafist movement.
Israeli intelligence no longer sees Sinai as the "backyard" of the Gaza organizations, but as the home of an independent jihadist network.
