Transcript for UN Shelter Hit By Israeli Missiles in Gaza
And now, we head overseas to the conflict in the middle east. Tonight, U.S. Airlines are starting to fly into tel aviv once more. That 48-hour ban has been lifted. But searing news is pouring in of another deadly hit in gaza. This time, a strike on a U.N. Shelter, where families were huddled inside. ABC's David Wright is on the ground in gaza for us tonight. Reporter: Today at jabalia hospital, there were so many casualties, they had to stack them two to a bed. Mothers, and grandmothers, and grandchildren. They had sought refuge from this war at about U.N. School. Today their safe haven came under attack. This is one of the smaller local hospitals, but you can see how stretched they are for resources. Only 13 beds in this emergency room. Today, they got more than 70 injured. Many of them just children. This father begged the busy doctors to please tend to his son. The boy is 13 years old. In all, more than 100 injured. 16 dead. In this one attack alone. This is where it happened. The buildings, clearly marked with U.N. Colors, blue and white. We saw shrapnel in the courtyard. And blood. But no one here. The refugees fled, leaving their belongings behind. Stray horses rummaged through them for food. The U.N. Is outraged, telling us they passed the school's location to Israeli forces 13 times, including this morning. Where else can these people go? If they are not safe with us then where are they safe? Reporter: But Israel says it warned the U.N. To evacuate this particular school. That it had strike militant targets nearby, as part of its efforts to stop hamas from firing rockets into Israel. Of course, the people had nowhere to go. And tonight, these children are homeless again. David Wright, ABC news, bit Hano hanoun, gaza.
