Palestinians hold balloons before they are released during a Nakba rally in al-Ram in the West Bank on the outskirts of Jerusalem May 6, 2010. Palestinians will mark "Nakba", or "Catastrophe", on May 15 to commemorate the time when hundreds of thousands of Palestinians were expelled or fled from their homes in the war that led to the founding of Israel in 1948.
