Two months after Israel cut off all supplies from entering Gaza, Mr Matar is warning that the few dozen remaining food kitchens are set to close in days. Recently, the UN's World Food Programme and Unrwa, the UN agency for Palestinian refugees, said they had used up all their stocks of food aid. "We used to receive more than 100 trucks every week - trucks of food parcels and hygiene kits. "We struggle to provide food such as rice, lentils, pasta, cooking oil and salt, for our community kitchens. In al-Mawasi camp, children gather playfully around Sami Matar and the Anera workers giving out the last of the day's food parcels.
