Yo-Yo Ma performed Bach at a 9/11 ceremony in New York as relatives and public figures began reading the names of those killed in the attacks at Ground Zero.
The cellist played the Sarabande from Bach’s C minor Cello Suite after a moment of silence at 8.46am, the time the first hijacked plane struck the World Trade Centre’s North Tower.
Former New York mayor Rudy Giuliani opened the roll call of 2,801 people killed or missing in the attacks. The reading took place at the site where the twin towers had stood, with families carrying photographs, laying flowers and placing personal belongings in a circle of remembrance.
Nearly 200 people followed Mr Giuliani at the microphone, including relatives of victims, survivors, politicians and actor Robert De Niro. The ceremony was interrupted at 9.03am, when a bell marked the moment the second plane hit the South Tower.
The names were read out over more than two and a half hours, with further pauses observed at the times the towers collapsed. Many of those taking part spoke the names of husbands, wives, parents, children and friends lost in the attacks.
The ceremony ended with the sound of taps and bells ringing across New York, as mourners gathered to mark the first anniversary of the September 11, 2001 attacks.
