Twenty-one years after the 9/11 terror attacks killed almost 3,000 Americans, the wounds wrought by that carnage are still fresh to many people. In remembrance of the attacks that rocked the world, ceremonies, vigils and memorials were held across the country. "As we stand on this sacred and scarred earth, a record of our collective grief and a monument to the memories that live on each day, this is the legacy we much carry forward: Hope that defies hate," Jill Biden said in Shanksville, Pennsylvania. In New York, six moments of silence were observed during the ceremony to mark when each of the World Trade Center towers were struck, when they fell, when a plane slammed into the Pentagon and when United Airlines Flight 93 crashed in Pennsylvania. 🔗 Visit our link in bio for more photos from 9/11 memorials. 📸 @apnews
