UNICEF chief Catherine Russell tells "Face the Nation" that the number of children who have died so far in Gaza in the Israel-Hamas war is an "astronomical, horrifying number." "We haven't seen that rate of death among children in almost any other conflict in the world," she added. "Face the Nation" is America's premier Sunday morning public affairs program.
