Palestinian construction labourers work on a water well at a Saudi Arabia-funded housing project executed by the United Nations Development Programme (UNDP), in Rafah in the southern Gaza Strip August 9, 2016. Israel said it had arrested and charged a United Nations employee for allegedly aiding Islamist movement Hamas, in the second such case involving a humanitarian worker in a week. Engineer Waheed Borsh, who has worked for the UN Development Programme (UNDP) since 2003, was arrested on July 16 and indicted in a civilian court in Israel, a government statement said. Hamas, which has run the Gaza Strip since 2007, denied the allegations. (Photo by SAID KHATIB / AFP)
