CAIRO: At least 67 people were killed by Israeli fire while they waited for U.N. aid trucks in northern Gaza on Sunday, the territory’s health ministry said, as Israel issued new evacuation orders for areas packed with displaced Gazans, some of whom began to leave.The ministry said dozens of people were also wounded in the incident in northern Gaza, in one of the highest reported tolls among repeated recent cases in which aid seekers have been killed, including 36 on Saturday. Six other people were killed near another aid site in the south, it said.The Israeli military said its troops had fired warning shots towards a crowd of thousands in northern Gaza on Sunday to remove what it said was “an immediate threat”.In total, health authorities said 88 people had been killed by Israeli gunfire and airstrikes across Gaza on Sunday. After Israel’s military dropped leaflets urging people to evacuate from neighbourhoods in central Gaza’s Deir al-Balah, residents said Israeli planes struck three houses in the area.Dozens of families began leaving their homes, carrying some of their belongings. Hundreds of thousands of displaced Gazans have been sheltering in the Deir al-Balah area.Israel’s military said it was continuing “to operate with great force to destroy the enemy’s capabilities and infrastructure in the area”.STARVATIONMuch of Gaza has been reduced to a wasteland during more than 21 months of war and there are fears of accelerating starvation. Palestinian health officials said hundreds of people could soon die as hospitals were inundated with patients suffering from dizziness and exhaustion due to the scarcity of food and a collapse in aid deliveries.“We warn that hundreds of people whose bodies have wasted away are at risk of imminent death due to hunger,” the health ministry, which is controlled by Hamas, said.The United Nations also said on Sunday that civilians were starving and needed an urgent influx of aid. Residents said it was becoming impossible to find essential food such as flour. The Gaza health ministry said at least 71 children had died of malnutrition during the war, and 60,000 others were suffering from symptoms of malnutrition.Later on Sunday, it said 18 people have died of hunger in the past 24 hours. Food prices have increased well beyond what most of the population of more than two million can afford.Several people who spoke to Reuters via chat apps said they either had one meal or no meal in the past 24 hours.“As a father, I wake up in the early morning to look for food, for even a loaf of bread for my five children, but all in vain,” said Ziad, a nurse. “People who didn’t die of bombs will die of hunger. We want an end to this war now, a truce, even for two months,” he told Reuters.Others said they felt dizzy walking in the streets and that many fainted as they walked. Fathers leave tents to avoid questions by their children about what to eat.UNRWA, the U.N. refugee agency dedicated to Palestinians, demanded Israel allow more aid trucks into Gaza, saying it had enough food for the entire population for over three months which was not allowed in.Israel’s military said that it “views the transfer of humanitarian aid into the Gaza Strip as a matter of utmost importance, and works to enable and facilitate its entry in coordination with the international community”.TRUCE TALKSSome Palestinians suggested the move on Deir al-Balah might be an attempt to put pressure on Hamas to make more concessions in long-running ceasefire negotiations.The Israeli military campaign against Hamas in Gaza has since killed more than 58,000 Palestinians according to health officials, displaced almost the entire population and plunged the enclave into a humanitarian crisis.
