The unidentified remains of those killed in the Sept. 11, 2001, terrorist attack have returned to the World Trade Center site in a solemn procession.
The remains were moved at dawn Saturday from the Chief Medical Examiner's office in Manhattan.
They were accompanied by police and fire department vehicles with lights flashing but no sirens.
The remains will be transferred to an underground repository in the same building as the National September 11 Memorial Museum.
The disposition of the remains has been contentious.
A group of victims' family members say the remains should be stored in a separate above-ground monument.
About a dozen wearing black bands over their mouths were protesting the transfer at the site Saturday.
Other family members support the plans, which have been in the works for years.
