Palestinians briefly block a main West Bank road during a demonstration calling for the release of prisoners jailed in Israel near Bethlehem, Monday, Feb. 18, 2013. Israel is holding some 4,500 Palestinians for charges ranging from throwing stones to undertaking deadly militant attacks. Their incarceration is a sensitive issue for Palestinians, who see them as heroes of the Palestinian liberation struggle. Posters show the face one detainee and slogans calling for the release of prisoners. (AP Photo/Nasser Shiyoukhi)
