GAZA CITY, Gaza Strip (AP) — At least 13 people were killed early Wednesday after tank shells hit a U.N. school in Gaza where hundreds of Palestinians had taken refuge from Israeli attacks.
Gaza health official Ashraf al-Kidra said another 90 Palestinians were wounded in the shelling.
Adnan Abu Hasna, a spokesman for a U.N. aid agency, says tank shells hit the Abu Hussein U.N. school in the Jabaliya refugee camp around 4:30 a.m.
An AP reporter who arrived later at the school saw a large round hole in the ceiling of one classroom and in one of the bathrooms. In another classroom, the strike had blown out the front wall.
The incident comes a day after Israel unleashed its heaviest air and artillery assault in the bloodiest day of the three-week Gaza war, destroying key symbols of Hamas control and shutting down the territory's only power plant.
