The import of humanitarian aid to Gaza has been blocked by Israel since March 2.
"Today, WFP delivered its last remaining food supplies to kitchens for warm meals in the Gaza Strip. These kitchens are expected to run out of food in the coming days," the organization warns in a statement.
Earlier in the week, the UN's humanitarian coordination organization Ocha stated that the humanitarian situation in Gaza is likely at its worst level so far during the war.
"For weeks, kitchens for warm meals have been the only consistent source of food aid for people in Gaza. Although they only reach half of the population with only 25 percent of the daily food needs, they have constituted an important lifeline," writes WFP.
