A special envoy dispatched by U.S. President George W. Bush apologized Wednesday in Tokyo to representatives of relatives of nine people still missing after the sinking of a high school fisheries training ship by a U.S. submarine.

Adm. William J. Fallon, the vice chief of naval operations, met the families at the U.S. ambassador's residence in Tokyo's Minato Ward as part of his visit to apologize for the accident.

Fallon, flanked by U.S. Ambassador Thomas Foley, offered the apology as "a representative of the United States, United States Navy" and President Bush.
