An Israeli airstrike on a Gaza City school compound housing displaced Palestinian families killed around 100 people, the Gaza Civil Emergency Service said on Saturday, while Israel said the toll was inflated and 19 militants were among the dead.
Video from the site showed body parts scattered among rubble and more bodies being carried away and covered by blankets. Empty food tins lay in a puddle of blood, and burned mattresses and a child's doll lay in the debris.
In another video, men prayed over a dozen body bags laid on the ground of the Tabeen school complex.
The Israeli strike drew condemnation from Arab states, Turkey, France, Britain and the European Union and an expression of deep concern from the U.S., which has been working with partners to prevent the 10-month-old Gaza conflict from escalating into a regional war.
Gaza's Civil Emergency Service, which has a credible record in stating casualty numbers, and the Hamas-run government media office said in separate statements that the complex had been attacked while its occupants were performing dawn prayers.
