As the volume of aid reaching the Gaza Strip remains woefully inadequate, the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) called Friday on the Israeli authorities, other parties to the conflict and those with influence over them to safeguard an environment for safe and unimpeded delivery of humanitarian aid. According to the UN agency, the entire population of Gaza of 2.2 million people is now almost exclusively dependent on humanitarian assistance, including food.
