15th anniversary 9/11 ceremony begins in silence, bell ring

NEW YORK (AP) — The U.S. marked the 15th anniversary of 9/11 on Sunday, with a moment of silence marking the instant when a hijacked plane crashed and revealed that the deadliest terror attack on American soil was underway.
At ground zero, hundreds of victims’ relatives and dignitaries gathered to hear the reading the names of the nearly 3,000 people killed under an overcast sky that shrouded the 1,776-foot-tall top of One World Trade Center, the centerpiece of the rebuilt site.
