Gaza City ( CNN ) -- It 's the hardest question in Gaza . In the twilight hours of Saturday , when the people of Gaza were breaking the daily Ramadan fast , fireballs illuminated the night sky . The Israeli military was intensifying its assault on Gaza militants in the Shaja'ia neighborhood near Gaza City . The battle had only just begun . As dawn broke Sunday , some barefoot , many looking dazed and haggard flooded from their smoldering neighborhood . Thousands walked along sidewalks , packed into cars , and piled onto donkey carts with only what they could carry : Some clothing , a bit of food . Most just had clothes on their backs . When CNN put this question to one Shaja'ia resident , with his family in tow , he broke into tears . `` Where are you going ? I just do n't know , '' he replied . Nearby explosions prodded the family forward into the unknown . A barrage of rockets . Gaza militants respond with a barrage of rockets . Another fleeing family waited for a car to ferry them to safety , but one member was missing . `` My mother refused to leave , '' said Sameh Grega . `` She told me to leave her to die , but I will try to go back . '' A temporary cease-fire later gave a CNN crew a glimpse of the inferno being fled . For many of those able to make it out , their destination will be the United Nations schools that have been turned into centers for those displaced . By Sunday afternoon , at least 81,000 people had arrived at 61 U.N. schools , and the number was likely to rise . It 's the largest number of internally displaced Gazans since Israel pulled out of the coastal strip in 2005 . A human surge found its way to the UN-run Rimal Girls School . The classrooms overflowed with civilians moving quickly without direction around the compound . The schoolyard is also a place for the latest news from home . One man found out his brother had been killed . No information yet about other members of his family . When word came that the shelter was full , rumors of a nearby school with space sent a stampede of families off again into the unknown . More than 60 killed . For hundreds of Shaja'ia 's residents , safety never came . The lucky ones received a ride to a hospital . The Ministry of Health put the neighborhood wounded at more than 400 . More than 60 were killed . `` There are more women and children this time around and the doctors are shocked and depressed , '' said Samantah Maurin with international aid group Doctors Without Borders . Maurin pointed to the lack of medical supplies which she describes as `` chronic and becoming more acute . '' Officials at the hospital braced for an influx of injuries they know will come from Shaja'ia . `` Many people are underground , '' said Dr. Nassar El Tatar , general manager of Shifa Hospital . `` We could not reach those people to extract them and there are surely dead people and wounded people and others will die if we ca n't get to them . '' To retrieve those stuck in Shaja'ia , the International Committee of the Red Cross called for a ceasefire . For a moment the guns fall silent over Shaja'ia . Pleas for help . Entering the densely populated neighborhood of roughly 100,000 residents , a CNN crew found a woman pleading for help . `` My son is in the house , '' said Amira Hillis . `` He 's wounded . I called the Red Cross , I called for an ambulance but no one came . Can you help ? '' On one street , a twisted pile of metal lay on the side of the road . Only the burned frame of a steering wheel revealed that it was any type of vehicle at all . In front of it was another ambulance -- its windows blasted out and its back door ajar . Bandages spilled into the rubble-strewn street . Debris was everywhere . Every window was shattered . Glass , pavement , and leaves mixed with gasoline . Snapped power and telephone lines hung from crooked poles . The smell of death mingled with the fumes of fuel . Paramedics rushed one motionless body away on a stretcher . A steady stream of ambulances rushed in and out of the shattered neighborhood , sirens wailing . A sense of urgency . A sense of urgency gripped the remaining fleeing residents who refused to stop long enough to talk . They were on edge , alert for the presence of any nearby Israeli soldiers . A local journalist whispered , `` Do n't stay long . It 's not safe here . '' He saw two men armed with AK-47 assault rifles slink away with purpose . The four-hour truce was shaky at best and at one point , it was said to have collapsed . It ultimately was extended until 5:30 p.m. Bassam , a young father holding his 1-year-old daughter , Hala , said he was going to take his family to a nearby U.N. school . But a man interrupted . `` It 's full , It 's full , '' he shouted . Bassam , like many others , then had to ask himself Gaza 's toughest question , where would he go ? Netanyahu : Israel seeks 'sustainable quiet ' with Gaza . Life in Gaza : Search for safety , or wait for destiny .
