Ohio Gov. John Kasich will mark the 12th anniversary of the 9/11 terrorist attacks with a remembrance ceremony at city hall in Columbus. Kasich will be joined by various officials at the city's council chambers. He has ordered flags be flown at half-staff and asked that all Ohioans observed a moment of silence at 8:46 a.m. Twelve years after terrorists flew hijacked planes into the World Trade Center towers in New York, the Pentagon in Washington and a field in Pennsylvania, Kasich says Americans must honor uniformed service members who "work diligently to protect us from danger." Nearly 3,000 people died in the attacks. A wreath laying ceremony will be held at the Ohio Fallen Firefighter Memorial in Reynoldsburg, east of Columbus. Other ceremonies are scheduled across the state.
