On the 23rd anniversary of the terrorist attacks of September 11, 2001, New York City is remembering the nearly 3,000 people who lost their lives and the many more who died from 9/11-related illnesses.

The annual remembrance ceremony at the 9/11 Memorial & Museum began at 8:30 a.m. Wednesday in Lower Manhattan.

In remembrance, the names of the victims are read out, there are minutes of silence and the ringing of bells to remember the chronology of the attacks.

The first moment of silence was observed at 8:46 a.m., when the hijacked American Airlines Flight 11 struck the North Tower of the World Trade Center. Similar moments of silence were observed five more times during the attacks, including when the towers collapsed.

The square will remain closed to the public during the ceremony, but a live stream of the entire event will be shown. HereNY1 will also broadcast the ceremony live.

Following the memorial ceremony, a moment of silence will be held at 2:30 p.m. to remember those who have died or become ill as a result of a September 11-related illness or injury.

President Joe Biden and Vice President Kamala Harris will attend the ceremony in Lower Manhattan, as will former President Donald Trump and his running mate, Senator JD Vance.

At nightfall, the Tribute in Light begins. Two blue beams of light can shine up to six kilometers into the sky and mark the spot where the Twin Towers once stood. The lights will stay on until dawn on Thursday.
