IN paying tribute to victims of the 2001 attacks on the Twin Towers in New York City, US President Barack Obama declared September 6-8 as national days of prayer and remembrance.
In his presidential proclamation address, President Obama, while marking the tragedy's 12th anniversary, said the day would always be remembered as the day that shook America to its core.
"Where two towers once cast a shadow, men and women gather in the early light to pay their respects," he said.
"At the Pentagon, where a single stone still bears the scars of fire, a nation honours souls who now know peace."
President Obama's emotional proclamation highlighted the horror which affected every person who witnessed the violent attack, either in New York City or on their television screens at home.
"We remember planes cutting through a clear September sky, black smoke rising from the ruins below â€¦ their legacy lives on in those they saved and in the memories we keep.
"Many of those we lost set aside their own well-being in the hope they could save someone they would never know."
