Yesterday, an Israeli civilian building a fence along its border with Egypt in the Sinai Peninsula was killed in a terrorist attack by the Mujahadeen Shura Council, an affiliate of al Qaeda which dedicated the attack to the late Osama bin Laden. Israeli forces killed three of the Mujahadeen terrorists.
I find it interesting that the attack was carried out following elections in Egypt. Of course, it isn't the first time Israeli civilians have been killed as a result of attacks from Egypt since the fall of Hosni Mubarak. In August 2011, eight Israelis were killed in attacks launched from the Sinai by Palestinians.
Now that al Qaeda is involved and with an Egypt far more hostile towards Israel, I expect we're going to see a great deal more of these attacks from the Sinai.
