A picture taken on January 3, 2015 from the Rafah area, in the southern Gaza Strip along the border with Egypt, shows men looking at the Egyptian side (R) a day after Zaki al-Houbi, a 17-year-old Palestinian man, was allegedly shot dead by Egyptian border guards. An Egyptian security official said that troops opened fire on Gazans who had illegally crossed into the Egyptian Sinai, where the army has created a buffer zone to prevent the movement of militants.
