9/11 is a date that people all over the world will never forget, a day when terrorist group al-Qaeda attacked the 110-storey Twin Towers of the World Trade Center (WTC), killing 2,977 people.

Families of the victims and invited guests will gather at the city’s memorial plaza for the ceremony which will feature a moment’s silence and a reading of the names of those who died.

The plaza, which saw an estimated 20,000 visitors to the site on this day last year, will open to visitors later in the morning.

Meanwhile, thousands are paying tribute to the victims online as the hashtags #September11 and #NeverForget911 trend on Twitter.
