An engraved plaque, unveiled just last week on a monument at the Bloody Ridge National Park in Solomon Islands has been stolen.
Bloody Ridge was confirmed as a national park last week during commemorations of the 75th Battle of Guadalcanal.
The monument commemorated the several thousand who died when American and Japanese soldiers fought over the 25 hectare Bloody Ridge site which is above Henderson Field airport, the key objective of the battle.
The Solomons Star newspaper said the theft happened at the weekend.
The American Ambassador to PNG and Solomon Islands, Catherine Ebert-Gray, had earlier announced that Bloody Ridge was to be added to the American Battlefield Monuments Commission.
