Authorities in France-governed territory say five suspects are under house arrest as they move to try and restore calm.
France has declared a state of emergency in its Pacific Islands territory of New Caledonia and deployed police and military reinforcements in an attempt to end days of unrest over the French governmentâs move to change the rules on provincial elections.
Three Indigenous Kanak people and a police officer have been killed in violence that erupted on Monday night and has continued despite an overnight curfew. Hundreds have been injured.
The state of emergency came into force at 5am on Thursday (18:00 GMT on Wednesday) and gives the authorities wide powers of search and arrest.
The office of the high commissioner, which represents the French state in New Caledonia, said in a statement that five people had been placed under house arrest as âalleged sponsors of the violent disturbancesâ and that more searches would take place âin the coming hoursâ.
More than 200 âriotersâ had been arrested, it added.
The authorities are âdetermined to quickly restore public order and take all necessary measures to protect the population of New Caledonia,â the statement said.
David Guyenne, president of the New Caledonia Chamber of Commerce and Industry, told Al Jazeera that the island was not âpreparedâ for the protests, which have had dire effects on the local economy.
The state of emergency âis good for usâ, he said. âWe have found that those rioters are uncontrollable. They were manipulated, or they were incentivised by pro-independence politicians, and now they are totally out of control. Thatâs why we need to return to the state of law.â
Guyenne added that âhopefullyâ the situation would be under control soon as France deploys more soldiers.
Military reinforcements were on their way from Marseille to help secure New Caledoniaâs international airport, which has been closed since the start of the week, as well as its ports.
The state of emergency will remain in force for 12 days.
France expects to regain control of the situation âin the coming hoursâ, Interior Minister Gerald Darmanin told France 2 television on Thursday.
Controversial reform
Anger has been simmering for weeks over plans to amend the French constitution to allow people who have lived in New Caledonia for 10 years to vote in the territoryâs provincial elections, diluting a 1998 accord that limited voting rights.
Many Indigenous Kanak people, who make up about 40 percent of the territoryâs nearly 300,000 people, fear the move will undermine their position in the territory.
This weekâs violence came as the National Assembly voted in Paris to adopt the measure. A joint sitting of the National Assembly and the Senate needs to be convened for the new rules to take effect because they represent a constitutional change.
New Caledonia, which lies some 1,500km (930 miles) east of Australia, was colonised by France in the 19th century.
The last serious outbreak of unrest in the 1980s led to the 1998 agreement, known as the Noumea Accord, promising greater autonomy as well as three referendums on independence.
In all three, most recently in December 2021, voters opted to remain part of France.
Pro-independence parties boycotted the final referendum because it took place during the COVID-19 pandemic which had a devastating and disproportionate effect on the Kanak community.
There are large disparities of wealth between the Kanaks and people of European descent. About 40,000 people have moved to New Caledonia from France since the 1998 accord.
