I don't know what to think about this - it was reported earlier this week as Egypt strengthening it's defences against incoming Palestinian refugees
All that food aid that's festering in Egypt unable to be delivered into Gaza will be very useful if they are forced out of Gaza 
Egypt appears to be preparing space in Sinai for displaced Palestinians: Report
The Washington Post reports that the Egyptian government appears to be preparing for the possibility of an influx of Palestinians pushed out of Gaza into the Sinai Peninsula if an anticipated Israeli assault on Rafah moves forward.
Some Israeli officials have promoted expelling Gaza’s population since the beginning of the war, but Israel’s allies, including the US, have warned that they would not support the forced displacement of Palestinians out of Gaza.
“Egyptian officials have threatened to suspend the countries’ 40-year peace accord if an attack on Rafah forces refugees across the border; new footage obtained by The Washington Post suggests Egypt is preparing for such a scenario,” the Post reported.
This week, the UK-based group Sinai Foundation for Human Rights, which has a monitoring team in Sinai, reported that Egypt was constructing a large concrete barrier to contain Palestinian refugees who could be displaced to Egypt.
The Post reported that it has verified video footage and other data showing that Egypt is “clearing debris from a rectangular plot of land measuring about eight square miles [21sq km] adjacent to the Gaza border, with a concrete wall being built around the perimeter”.
An unidentified Egyptian official also suggested to the US newspaper that the the move is likely a contingency plan for what Egypt sees as a “worst-case scenario”.
Egypt has vehemently rejected the forced displacement of Palestinians into its territory.
