A warship built with steel salvaged from the World Trade Center has arrived in New York City.
The USS New York sailed up the Hudson River to near Ground Zero, where it fired a 21-gun salute in tribute to those killed in the 2001 attacks.
It was watched by relatives of 9/11 victims, along with members of the emergency services and the public.
The US Navy is to hold an official commissioning ceremony for the new warship on Saturday.
The New York set off on its maiden voyage from Louisiana, where it was built, nearly three weeks ago.
