Here's a piece by Nick Berg's father, Michael Berg, published in today's Guardian:

"Even more than the murderers who took my son's life, I condemn those who make policies to end lives ":

"...My son's work still goes on. Where there was one peacemaker before, I now see and have heard from thousands of peacemakers. Nick was a man who acted on his beliefs. We, the people of this world, now need to act on our beliefs. We need to let the evildoers on both sides of the Atlantic know that we are fed up with war. We are fed up with the killing and bombing and maiming of innocent people. We are fed up with the lies.

Yes, we are fed up with the suicide bombers, and with the failure of the Israelis and Palestinians to find a way to stop killing each other. We are fed up with negotiations and peace conferences that are entered into on both sides with preset conditions that preclude the outcome of peace. We want world peace now.

This is an extract from his message of support for the Stop The War Coalition's demonstration, "End the Torture - Bring the Troops Home Now", which will be held at 11am tomorrow at the Embankment in London
