The French authorities will continue to guarantee the security of property and people at tourist sites in and around Paris, the Paris municipality announced on Tuesday.

The safety of tourists is not at risk at all, said the Paris City Hall in a statement, though violent riots in poor suburbs have swept the country for a 12th consecutive night.

No decline in the number of tourists has been recorded so far, said the statement.

A dozen of nations, including Australia, Austria, Britain, Canada, Germany, Hungary, Japan, Russia, Spain and the United States, have warned their nationals against trips to France.

France, world's top tourist destination, attracts 75 million foreigners each year. The country's tourism minister Leon Bertrand had reaffirmed that France is safe for tourists.

The riots in France was set off by anger within the immigrant community over the Oct. 27 deaths of two teenagers electrocuted in a transformer shed where they took refuge as they thought they were being pursued by police.

A total of 1,173 vehicles were burnt and 330 people arrested overnight as the riots entered its 12th straight night. The French government Tuesday approved giving powers to regional authorities to declare state of emergency over specific regions if necessary.
