Aid organisations demanded Wednesday safe and unhindered aid access in war-torn Gaza, wracked by hunger and where babies are freezing to death, even as more hospitals face closure amid fuel shortages. Heavy rain and flooding have ravaged the makeshift shelters in Gaza, leaving thousands with up to 30 centimetres (one foot) of water inside their damaged tents, the International Federation of Red Cross and Red Crescent Societies said. The Doctors Without Borders (MSF) charity meanwhile warned that three large hospitals further south were on the verge of closing due to a lack of fuel.
