Friday marks the 14th anniversary of September 11, 2001. A live stream of memorial events at the National September 11 Memorial & Museum is being shown online and events across New York City have been scheduled to commemorate the day's tragic events and pay respect to the 2,977 people killed when commercial airplanes hijacked by terrorists were flown into the World Trade Center, the Pentagon and a field in Pennsylvania.

Family members of victims killed in the 2001 and 1993 attacks at the World Trade Center are participating in a private commemoration ceremony at the National September 11 Memorial & Museum. The event is broadcast live on the 9/11 Memorial Museum's homepage. To watch, click here.

To honour those killed, family members will read out the names of victims. Six moments of silence will occur during the commemoration: two marking the planes hitting the towers, two marking the collapse of the towers and two marking the attack on the Pentagon and the crash of Flight 93 in Pennsylvania.

Meanwhile, the bell of hope will be rung at St Paul's Chapel in New York City in remembrance of those killed 14 years ago. Prayers for peace are also scheduled to be said. St. Paul's Chapel was nicknamed the 'little chapel that stood,' for remaining intact following the destruction of the twin towers. The chapel served as a point of sanctuary for relief workers after the 2001 attack.

The 9/11 Memorial Museum will open to the public at 3pm following the private ceremony. The annual Tribute in Light illuminates New York City's skyline with two columns of light depicting where the twin towers once stood. The tribute can be seen in the sky south of the Memorial Museum.

As part of the National Day of Service and Remembrance, volunteers' events were scheduled to be held across New York City. The New York Blood Center was expected to be accepting donations from 9am to 4pm.

This year also marked the inaugural Dine Out for 9/11 Tribute, which will raise awareness and funds for education programs put on by the 9/11 Tribute Center. Participating restaurants include Morton's The Steakhouse, Clinton Hall and the Irish American Pub and Restaurant, among others.

A Florida man was arrested on Thursday, September 10, accused of posing as an Australia-based Isis jihadi and planning to bomb a 9/11 memorial event in Kansas.
