NEW YORK (AP) - The schedule for Queen Elizabeth II's visit to

New York City includes a tribute to the victims of the 9/11 attacks

and addresses to the United Nations.

The queen will spend five hours in the city Tuesday.

The 84-year-old monarch was 31 years old when she last addressed

the U.N. in 1957. That was four years after she was crowned queen.

This time, she's expected to appeal for world unity and peace.

The queen also is scheduled to lay a wreath at ground zero to

pay tribute to victims of the 2001 terrorist attacks. She will also

open the British Garden of Remembrance in nearby Hanover Square to

honor the 67 British citizens killed on 9/11.

Her husband, the Duke of Edinburgh, is traveling with her.
