This predates the Corrie incident by nearly a month. The tunnels in Rafah have been widely reported. Palestinian Rafah and Egyptian Rafah are seperated by a fence, and there are around twenty tunnels that seperate them. 50% of the total daily shooting attacks and roadside bombs come from Rafah, and it's rarely reported by the press at all because it's simply just a warzone ... not many civilians populate this area...and whatever civilians have populated the area are held hostage living within an operation to smuggle various illegal items to and from the Muslim Brotherhood. The fighting in this area isn't so much because of any "Free palestine" movement... but out of desperation to keep the tunnels open so they can get paid.
