Palestinian art student Khaled Jarrar poses for a photo with a 'State of Palestine' stamp at the central bus station in the West Bank city of Ramallah May 31, 2011. Living in occupied territory, the Palestinians do not have their own frontier controls.

Thousands of pro-Palestinian activists and demonstrators march to the Taksim Square in Istanbul, Turkey, Monday, May 30, 2011 as they marked the first anniversary of a deadly raid by Israel on a Turkish aid ship bound for the Gaza Strip. The same ship has been refitted and is preparing to sail for Gaza once again next month. An international coalition of activists said Egypt's removal of a 4-year-old blockade of the Gaza Strip last weekend will not affect their plans for a new flotilla, which will depart from various European ports in an attempt to breach Israel's sea blockade.

A Palestinian woman carries her bag as she crossed at the Egyptian side of Rafah border crossing , Saturday, May 28, 2011. After a four-year blockade, Egypt on Saturday permanently opened the Gaza Strip's main gateway to the outside world, bringing long-awaited relief to the territory's Palestinian population and a significant achievement for the area's ruling Hamas militant group. The reopening of the Rafah border crossing eases an Egyptian blockade of Gaza that has prevented the vast majority of the densely populated area's 1.5 million people from being able to travel abroad. The closure, along with an Israeli blockade of its borders with Gaza, has fueled an economic crisis in the territory. (AP Photo/Amr Nabil)
