A combo of pictures shows Palestinian youths Mohammed Udeh (top), and Nadeem Nuwarah, lying on the ground after they were shot by Israeli forces during clashes following a protest outside the Israeli-run Ofer prison on May 15, 2014, in the Palestinian village of Betunia in the occupied West Bank marking "Nakba" or "catastrophe" of the Jewish state's creation. A senior Palestinian official on May 20, 2014 accused Israel of the "deliberate execution" of two Palestinian teenagers shot dead by border policemen in a clash in the West Bank last week.
