More on the inconvenient history of refugees in the Middle East.

From the Times of Israel, Egyptian authorities reportedly seize 1.7 million documents proving Jewish ownership of assets in Cairo:

Egyptian authorities confiscated some 1.7 million documents reportedly proving Jewish ownership of land and assets in Cairo. The documents were reportedly about to be shipped out of the country to Israel, in what the Egyptian daily Al-Ahram is calling “the most dangerous case of security breach in history.”

The documents were found in 13 large cases, ready to be transported to Jordan and from there to Israel, Egyptian media reported Sunday.

Elaph, a Saudi-owned news site, reported that Egyptian police received notice that the packages were being held at a shipping company in the Nasser City district of Cairo. Upon arriving at the scene, police found over 1.7 million documents dating back to the 19th century, dealing with Jewish ownership of assets in Cairo. The documents, according to the security source speaking to the Saudi site, weighed over two tons.

Preliminary investigations have revealed that the documents were supposed to be used in an Israeli lawsuit involving Jewish property lost in Egypt’s 1952 revolution, the site reported. According to Elaph, Egyptian President Mohammed Morsi is personally following the case, which it said affects Egypt’s national security.

The documents were reportedly stolen on December 16, 2011, from a Cairo research institution, the Institut d’Égypte, during public riots that erupted following president Hosni Mubarak’s ouster.
