By Nidal al-MughrabiGAZA (Reuters) - Doctors in Gaza say patients arriving at hospitals are showing signs of disease caused by overcrowding and poor sanitation after more than 1.4 million people fled their homes for temporary shelters under Israel's heaviest-ever bombardment. With all hospitals running out of fuel to power their generators, doctors have warned that critical equipment, like incubators for newborns, risk stopping. The World Health Organization warned that a third of Gaza hospitals were not operating. The only other hospital that had still been serving patients in northern Gaza, Beit Hanoun Hospital, stopped operations because of the intense bombardment of the town, the Palestinian Health Ministry said. "If the hospital doesn't get fuel, this is going to be a death sentence against the patients in northern Gaza," said Atef al-Kahlout, the hospital's director.
