Five people were injured when a United Nations school serving as a shelter was hit by Israeli fire Wednesday in Gaza, the second time in three days that a U.N. school reportedly took a direct hit from Israeli rounds.

The U.N.’s Relief and Works Agency said Thursday the UNRWA Girls’ School in Deir al-Balah in Gaza was sheltering about 1,500 people from Israeli attacks when it was hit.
