The Mayor of London, Sadiq Khan, said: “Today we mark the 20th anniversary of 9/11, and remember the thousands of innocent people who tragically lost their lives. We will never forget the terrible events of that fateful day.
“My thoughts are with all those who lost friends and family members, and those who suffered life-changing injuries because of the horrific acts of terrorism that September day, including the 67 Britons who were killed, many of whom were from London.
“I also want to pay tribute to the heroic efforts of the emergency services who ran towards danger to help people and save lives.
“In London, we stand united with our friends in America and remain determined to show the world that those who seek to destroy our way of life will never win. Our values of freedom, tolerance and mutual respect will always prevail over those who seek to divide us.”
