Occupancy rates at some Paris hotels have plunged by more than 30 per cent in the days since the Nov. 13 attacks, according to a company that tracks hotel industry data.
STR Global said that compared with the same dates in 2014, occupancy rates were 39 per cent lower last Saturday and 33 per cent lower on Sunday, the two most recent days in the STR report.
Restaurants, small shops, department stores and tourist sites have also been affected. The French government said after a Cabinet meeting Wednesday that businesses that had suffered a financial hit could get extensions on tax and loan payments as a means of softening the blow.
France is among the world's top tourist destinations. Several museums in Paris closed in the days after the attacks.
Meanwhile, French lawmakers have overwhelmingly voted to continue airstrikes against the Islamic State group in Syria beyond early January.
The parliament's upper house voted 325-0, with 21 abstentions, on Wednesday night to extend the fight against IS. The Islamic militants have claimed responsibility for the Nov. 13 attacks in Paris that killed 130 people and wounded hundreds more.
French fighter jets joined the U.S.-led coalition against Islamic State extremists in Iraq in 2014, and expanded their mission to Islamic State targets in Syria in September. French President Francois Hollande has cited specific threats against French interests stemming from IS in Syria.
