Unidentified remains from the 9/11 attacks have been returned to "Ground Zero" in New York in a solemn ceremony.
Fifteen vehicles took the remains from the Office of the Chief Medical Examiner to a repository beneath the World Trade Center site.
The BBC reports the move has split opinion among the families of the dead, with some holding a protest at the memorial site.
The attacks on 11 September 2001 killed almost 3000 people in New York, Washington DC and Pennsylvania.
Of the 2753 who died at the World Trade Centre, 1115 have not been identified.
The remains consist of 7930 fragments of human tissue that could not be identified by forensic teams.
They were placed in metallic boxes, covered in the American flag and taken in a convoy comprising fire trucks and police vehicles to the site of the attacks in downtown Manhattan.
Uniformed firemen and police then placed the boxes in a dedicated facility located underneath the 9/11 Memorial Museum.
The repository is 20m underground and will remain under the control of the Office of the New York Medical Examiner. Only family members and forensics teams will be allowed direct access.
The BBC reports some family members held a silent protest at the site of the move, ending their vigil just before the transfer ceremony took place.
