Palestinian prime minister Rami Hamdallah attends the Palestinian Turkish conference of surgery in Palestine during his visit to the Gaza Strip, in Gaza city on March 26, 2015. Hamdallah urged rival factions to set aside their differences, even as protesters gave him a cool reception in war-battered Gaza. It was only Hamdallah's second visit to the Gaza Strip since a unity government agreed on by rivals Fatah and Hamas took office last June. Photo by Ashraf Amra
