The traditional church service in London incorporated an Act of Remembrance, the Last Post and the words of modern Turkey's founder Kemal Ataturk from Anzac Cove, read by the Turkish ambassador to the UK.
A service at the Cenotaph in London has marked Anzac Day, the annual day of remembrance for armed forces personnel from Australia and New Zealand.
The day marks the anniversary of the start of the First World War Gallipoli landings and is a national day of remembrance for the two countries.
Representatives of the UK armed forces have paid tribute to the service and sacrifice of Australian and New Zealand personnel at a Dawn Service and during commemoration ceremonies at the Cenotaph and Westminster Abbey.
Thousands of Anzac troops (Australian and New Zealand Army Corps) died in the ill-fated 1915 campaign.
Waves of Allied forces launched an amphibious attack on the strategically important Turkish peninsula, which was key to controlling the Dardanelles straits, the crucial route to the Black Sea and Russia.
But the plan was flawed and the campaign, which faced a heroic defence by the Turks, led to stalemate and withdrawal eight months later.
Its legacy is the celebration of the "Anzac spirit" - courage, endurance, initiative, discipline and mateship - shown by the Antipodean troops.
