Photographs and flowers were left at the base of the sculpture "The
Sphere" after a memorial service marking the passing of six-months
since the attacks on the World Trade Center in New York on March 11,
2002. "The Sphere" once stood on the plaza of the World Trade Center
and, though damaged, is now part of a temporary memorial to the nearly
3,000 people killed on September 11. REUTERS/Peter Morgan
