The fallout from the demise of Egypt’s Mubarak regime continues to haunt Israel each passing day.

First, Israel expressed concern as Islamist parties came out victorious in the first round of Egypt’s parliamentary elections and thus urged any future government to uphold the 1979 peace treaty. Then, Egypt’s Muslim Brotherhood said the country’s peace treaty with Israel needs to be re-evaluated by the country’s new parliament because the brotherhood “believes the treaty is of great importance, but it is not on the top of our list. There are other priorities for the time being.”

And now, according to the Jerusalem Post report, Hamas has established forward bases and rocket production facilities in the Sinai Peninsula with the believe that Israel will not strike targets inside Egypt due to the affect it would have on bilateral relations.

While Hamas is believed to be involved in planning some of the attacks that have triggered Israel’s high alert along the border with Egypt, it is not participating in firing rockets at Israeli communities. That is being done by smaller groups that do not heed Hamas’s authority.

The report did not explain whether the rockets these smaller groups have been using were produced by the Hamas’ rocket factories.
