Anger as new 9/11 remains found
The discovery comes weeks after the fifth anniversary
Scene of excavation
Human remains - some as large as arm or leg bones - have been found at the site of the 11 September attacks in New York, AP news agency has reported.
The remains were found in rubble excavated from a manhole near the site of the World Trade Center.
Relatives say the find proves the need for a thorough new search of the area around Ground Zero.
"We can no longer rely on accidental discoveries," said WTC Families for Proper Burial in a statement.
"This must be a deliberate search. May this awful news be the catalyst needed to go back and do the job well."
Families of more than 1,100 of the victims of 9/11 have never received any remains of their loved ones.
The campaign group is to hold a news conference over the latest discovery later on Friday.
Abandoned site
The material excavated from the manholes was removed from the site without anyone noticing it contained the remains, said utility company Consolidated Edison.
On Thursday, the Port Authority contractor spotted the remains, the agency said.
Some of the remains were as big as arm or leg bones, said Steve Coleman, a spokesman for the Port Authority.
Construction workers have been instructed to look for human remains and notify the medical examiner's office when they find them.
"No official identifications have been made at this time and the New York City Police Department and the Office of the Chief Medical Examiner are heading up the investigation," said Patrick J Brennan of the Mayor's Community Assistance Unit was quoted by the AP news agency.
The discovery comes just weeks after the fifth anniversary of the attacks.
Earlier this year, construction workers in New York discovered 74 bone fragments from 9/11 victims. The remains were found mixed in with roofing material at the condemned Deutsche Bank building, which stands next to Ground Zero.
