The United Nations Children’s Fund warns 21 months of Israeli attacks have killed more than 17,000 children in Gaza, with another 33,000 injured. UNICEF Executive Director Catherine Russell testified to the U.N. Security Council on Wednesday.

Catherine Russell: “An average of 28 children have been killed each day, the equivalent of an entire classroom. Consider that for a moment: a whole classroom of children killed every day for nearly two years. These children are not combatants. They are being killed and maimed as they line up for lifesaving food and medicine.”
