Following is the text of the address by Secretary-General Kofi Annan to the Commission on Human Rights in Geneva:
It is good that we have observed those minutes of silence together.
We must never forget our collective failure to protect at least 800,000 defenceless men, women and children who perished in Rwanda 10 years ago.
Such crimes cannot be reversed.
Such failures cannot be repaired.
The dead cannot be brought back to life.
So what can we do?
