Last weekend, militants from the terrorist group Hamas killed more than a thousand people, including children, in an attack on Israel while also taking hostages. Israel has ordered a full siege of Gaza, where nearly half of residents are under 18 years of age. The news is alarming for anyone — especially for children, who may be left grappling with questions about why other children are among those affected, and whether they are safe. In this episode of Life Kit, NPR's Becky Sullivan gives us advice on how to talk to children about the violence in Israel and Gaza.
