DENVER (AP) -- Thousands of people streamed from the Denver Coliseum today in an anti-war protest march to the Pepsi Center, where the Democratic National Convention is being staged.

They were led by members of the Iraq Veterans Against the War.

A sit-in was planned at the convention site.

Iraq Veterans Against the War wants Democratic presidential candidate Barack Obama to agree to an immediate withdrawal of troops from Iraq. It also wants full health care benefits for returning troops and veterans, and reparations to the Iraqi people for damage caused by the war.

The group sent a letter to Obama on Monday.

The protest march began after a reunited Rage Against the Machine ended a concert that drew an estimated 9,000 people to the coliseum.

Dozens of veterans, some in uniform, began the march in formation, chanting "She Wore a Yellow Ribbon."

It's about 4 miles from the coliseum to the Pepsi Center.
