Dear Supporter,

I was shocked to hear reports that Iranian security forces arrested 29 mothers and their supporters who were silently mourning children killed in post-election violence this summer.

These Mourning Mothers gather peacefully each week to call for an end to widespread human rights abuses and justice for their dead children.

The disturbing news of their arrest brought to mind profound memories of the Mothers of the Disappeared in Chile and Argentina. Like the courageous mothers in Iran, the Mothers of the Disappeared faced threats and harassment for seeking justice for their children kidnapped during the Dirty Wars in Chile and Argentina.

My song "They Dance Alone" is dedicated to the Mothers of the Disappeared. I had the honor of performing it with them in 1988 during Amnesty International's Human Rights Now! Tour.

Dancing on stage with the Mothers of the Disappeared in Chile and Argentina was one of the most moving moments of my career.

I am heartbroken to see that once again others have to face the anguish that the Mothers of the Disappeared endured. I am compelled to speak out again. I hope you will too.

What gives me hope is knowing that Amnesty International is fighting on behalf of the Mourning Mothers and others threatened with abuse in Iran and around the world.

As you read this, Amnesty International is investigating and reporting on the human rights situation in Iran. It's publishing the names of prisoners of conscience and documenting the use of brutal force to crush dissent -- even as it continues to respond to human rights emergencies across the globe.

The people of Iran deserve to speak peacefully without fear. Show them they are not alone. Donate to Amnesty International today.

Sincerely,
