From July 25 trhough September 2, from Boston to New York City, families of those killed on September 11th, along with friends, supporters, veterans and others from around the world who have experienced terrorism, violence and war, have pulled a memorial stone to the "unknown civilians killed in war."

Civilians casualties constituted 80% of the deaths in wars during the 20th century, and the participants are asking all politicians to make this human toll a prime consideration in future U.S. policymaking decisions.

Stonewalk is sponsored by September 11th Families for Peaceful Tomorrows in conjuction with the Peace Abbey, a multi-faith retreat center.
