Palestinian protesters shout slogans as they march towards the Erez border crossing in the northern Gaza Strip on May 15, 2011 to mark the “Nakba” or “Catastrophe” anniversary of Israel’s creation in 1948, as a result of which more than 760,000 Palestinians — estimated today to number 4.7 million with their descendants — were pushed into exile or driven out of their homes.
