9/11 Anniversary: 15 Years On

It is 15 years today, since that fateful day when the New York twin towers collapsed, killing almost 3000 in a terrorist attack. Services were held in churches in US to commemorate the event, The names of the 2,983 victims were read slowly by relatives.

No public officials will speak at the New York ceremony, in keeping with a tradition that began in 2012. But many dignitaries attended, including Republican presidential hopeful Donald Trump and his Democratic rival Hillary Clinton.

"We'll never forget the horror of Sept. 11, 2001," Clinton said in a brief statement. "Let's honor the lives and tremendous spirit of the victims and responders."

Trump said in a statement that it was a day of sadness and remembrance, but also of resolve.

"Our solemn duty on behalf of all those who perished ... is to work together as one nation to keep all of our people safe from an enemy that seeks nothing less than to destroy our way of life".
