Notre-Dame cathedral in
Paris is still at risk of collapse after being gutted by a
fire in April, with more stonework falling during the recent heatwave in the French capital, the government said on Wednesday.
France's culture ministry insisted that the urgent need to make the cathedral safe had dictated the pace of the works, following criticism that it had ignored the risks of lead poisoning.
Work to secure the cathedral was suspended on July 25 to allow for decontamination of the lead that had spread during the fire.
