TONIGHT, AT LEAST 16 PALESTINIANS ARE DEAD AFTER AN ISRAELI AIRSTRIKE ON A U.N. SCHOOL THAT WAS BEING USED AS A SHELTER. THE GAZA HEALTH MINISTRY SAYS MOST OF THE VICTIMS WERE WOMEN AND CHILDREN. THE ATTACK COMES AMID RISING HOPES THAT A NEW CEASE-FIRE DEAL MAY BE WITHIN REACH. CBS'S HOLLY WILLIAMS HAS THE DETAILS. HOLLY?
