9/11 memorial 2023: anniversary events, is there a minute’s silence - and how to watch New York service online

This year marks the 22nd anniversary of the 9/11 attacks in New York. On 11 September 2001 almost 3,000 people were killed when terrorists hijacked four passenger planes and crashed them in to the twin towers at the World Trade Centre in New York, the Pentagon and a field in Pennsylvania.

The terrible events of that day shocked and saddened not only people in the United States, but also in the UK and around the world. Every year since, the sombre date has been marked with a series of memorial events.

But just what are the events taking part in 2023, and how can we watch them in the UK? Here is everything you need to know.

What is happening at Ground Zero?

Since 2002, each year on September 11, the names of the dead have been read at the event at the famous memorial pools, an event previously attended by Presidents Bush and Obama. The service will play out similarly this year for the 22nd anniversary of the terrorist attack.

Vice President Kamala Harris is due to join the ceremony on the National September 11 Memorial and Museum plaza in New York City this year. Commemorations will take place today (11 September), starting at 1.40pm UK time.

Following on from previous years, moments of silence will mark when a plane hit each of the Twin Towers, the Pentagon and a field in Shanksville, Pennsylvania, and when each tower fell. The service is expected to conclude at 6pm UK time.

Where else are there memorials?

A memorial will also be held at the Flight 93 National Memorial in Pennsylvania. A field in Pennsylvania is where the fourth plane crashed after it had been hijacked by terrorists

How will President Joe Biden mark the anniversary?

The White House says President Joe Biden will mark the 22nd anniversary of the 9/11 attacks on Monday 11 September by attending a ceremony on a military base in Anchorage, Alaska. He is set to speak in front of 1,000 first responders and their families at the military base. In a statement from the President on the White House website, he said: "In honour of all the lives we lost 22 years ago — and in honor of all the heroes who have given their whole souls to the cause of this Nation every moment since — may today not only be observed with solemn remembrance but also with renewal and resolve."

How can I watch the memorials in the US and the UK?

The 9/11 memorial services in New York City and Pennsylvania will be broadcast live online by several major television networks.

NBC News, CNBC, ABC News, CBS News, Fox Business, and many others have previously live streamed the 9/11 commemorations on their YouTube channels.

The events are also expected to be broadcast through the "Watch Live" section of the 9/11 Memorial & Museum website, where the museum has live streamed other events, so that people in the UK can also watch.

While there is no “official” minute’s silence, many people choose to observe a moment of quiet contemplation at 1.46pm UK time, the moment the first plane struck the Twin Towers.
