A Palestinian girl, hoping to cross into Egypt with her family, waits at the Rafah crossing between Egypt and the southern Gaza Strip on Dec. 22, 2014. Egypt temporarily reopened the Rafah border crossing on Sunday allowing Palestinians from Gaza Strip to travel in and out for the first time since it was closed on Oct. 25. Egypt closed Rafah crossing following a series of deadly attacks carried out by radical Islamic militants in Sinai. (Xinhua/Khaled Omar)
