Dear friends across India and the world, The brutal Mumbai terrorist attacks sought to divide us... I'm writing this because I feel we need to honour their memory... The attacks were aimed at our people, our prosperity and our peace.

But their top target was something else: our unity. If these attacks cause us to turn on each other in hatred and conflict, the terrorists will have won...

Let's deny them that victory. We're launching a message to extremists on all sides and all our political leaders, one that will soon be published in newspapers across India and Pakistan.

The message is that these tactics aren't working, that we're more united than ever, united in our love and support to each other, and determined to work together to stop violent extremism. If millions of people sign it, our message will be unmistakable...

As a Muslim, I am shocked at what has been done in the name of my faith. As an Indian, I am determined to keep these terrorists from tearing our nation apart. As a human being, I join with the entire world in condemning this horrific violence.

It's time to speak out... together.
With respect, sadness and hope,
Soha Ali Khan, actress and Avaaz senior advisor
