NEW YORK (AP) -- Prince Harry plans to mark his first official visit to the United States with a stop at the World Trade Center site.

The 24-year-old prince will meet Friday with relatives of four people who died in the September 11, 2001 attacks on the United States. Later he will formally name the British Garden in New York's Hanover Square to honor the 67 British victims of the terrorist attack.

Harry also will visit the Veterans Affairs Medical Center in Manhattan, where he will tour the prosthetics facilities and a post-traumatic stress clinic.

A British soldier who lost both legs in Afghanistan will accompany Harry.

Prince Harry is the younger son of the late Princess Diana and Prince Charles. He is third in line to the British throne.
