First moment of silence held at New York service for 9/11 dead
A commemoration on the 20th anniversary of 9/11 held a moment's silence for the almost 3,000 people killed in the attacks
Attendees, including President Joe Biden, stood still at 8:46 am (1246 GMT), the moment the first plane struck the World Trade Center, before relatives started reading the names of the dead.
Six moments of silence will be held throughout the service.
