Students who survived one of the deadliest school mass shootings in U.S. history graduated high school on Wednesday, as many called for more action on gun control.
Emotions ran high at Newtown High School in Connecticut, more than 11 years after a former student entered Sandy Hook Elementary School with guns and killed 20 children—all aged six or seven—and six teachers and staff.
Twenty seats at the high school graduation ceremony were left empty in honor of the children who died in the massacre, which shook the nation.
