LONDON (AP) — Britain's Prince Harry has laid a wreath during an early morning ANZAC Day service in London honoring fallen New Zealanders and Australians.

Thousands of people gathered at dawn Monday in central London for the annual events that mark the anniversary of the 1915 ANZAC landings at Gallipoli during World War I. Australia and New Zealand suffered major casualties during the ill-fated operation.

Harry placed a wreath at the memorial in Hyde Park Corner and was followed by diplomats from New Zealand and Australia.

The prince will be representing his grandmother Queen Elizabeth II at other ANZAC Day memorial events, including a parade and a thanksgiving service at Westminster Abbey.

Other countries, including Australia, New Zealand and France, also held ANZAC Day ceremonies.
