US President Barack Obama has told 9/11 victims' families that the whole country shares their loss on the 11th anniversary of the terrorist attacks.
Speaking at the Pentagon, where 184 people were killed, Mr Obama said:
Eleven times we have paused in remembrance and reflection, in unity and in purpose. This is never an easy day, but it is especially difficult for all of you, the families of nearly 3,000 innocents who lost their lives.
But no matter how many years pass, no matter how many times we come together on this hallowed ground, know this: That you will never be alone, your loved ones will never be forgotten.
They will endure in the hearts of our nation because through their sacrifice they helped us make the America we are today, an America that has emerged even stronger.
