At least 80 percent of people in Gaza need urgent food assistance and Israel must make access to the area easier for humanitarian aid to be delivered, the head of the United Nations' food relief agency said on Friday according to Reuters. The World Food Programme (WFP) said it was becoming increasingly difficult to find food in Gaza, with little available in markets, bakeries running out of wheat flour, flour mills running out of grain and many people too frightened to leave their homes. "The situation in Gaza is dire with at least 80 per cent of the people needing urgent food assistance," WFP Executive Director Josette Sheeran said during a visit to Rafah, on the Egyptian border with Gaza, to assess the crisis. Sheeran has sent senior WFP officials to Jerusalem to urge the Israeli authorities to free up access for aid, the WFP said in a statement issued by its Rome headquarters.
