According to Ynetnews.com, an El-Al Plane flying from Israel to Italy was found to have Arabic graffiti sprawled in the cargo part of the play. According to the report, they wrote "Death to Jews" and another report from Reuters says they wrote "Long Live Palestine."
No explosives were found on the plane.
I would venture a guess both were written as of the information right now; however, this is still a horrible thing to have occurred.
When will the world learn that the Muslim Extremists are anti-Semitic and want to kill Jews whether in Israel or in any country around the world?
