DENVER (AP) — About 1,000 anti-war activists marched peaceably through downtown Denver on Sunday, waving signs and chanting, "Stop the torture, stop the war. That's what we're fighting for."

In a wheelchair leading the march was anti-war activist Ron Kovic, the paralyzed Vietnam veteran whose story was chronicled in the book and movie "Born on the Fourth of July."

"The whole world is going to be watching, and we will march with dignity and discipline today," Kovic said.

At a rally before the march, anti-war activist Cindy Sheehan told the crowd little has changed since her monthlong protest outside President Bush's ranch in Crawford, Texas, in 2005.

"Now, three years later, our country is still mired in the Middle East. We're talking about more war, more cold war, and Russia and Georgia, and invading Iran and Pakistan," she said.
