French Polynesia's nuclear test veterans have called for 2 July to be made a public holiday to remember the impact of France's nuclear weapons tests on the local population.
The call was made as about 2,000 people gathered in Papeete to mark the 56th anniversary of the first test at Moruroa, which is still a French military no-go zone.
The annual commemoration was organised by Moruroa e tatou and Association 193, whose name refers to the number of atomic tests carried out over three decades.
The groups keep demanding that France pay compensation for those affected by the tests.
Since 1995, the local health system has paid out $US800 million to treat a total of 10,000 people suffering from any of the 23 cancers recognised by law as being the result of radiation.
The head of Moruroa e tatou Hiro Tefaarere described the tests as France's largest case of genocide.
The head of the Maohi Protestant Church Francois Pihaatae said the truth about the tests begins to be known.
After ending the tests in 1996, France continued to claim until 2009 that none of the tests had any negative effect on French Polynesians' health.
A compensation law was adopted in 2010 and despite its revision, most claims have failed.
