 the tallest such structure in the country. The BBC's Mark Lowen is in Paris. The fire seems to have broken out late morning, perhaps around noon, and it is on the spire of Notre Dame Cathedral in Rouen in northwestern France. But the spire itself is not thought to be threatened by the flames. About 33 fire trucks are there, more than 60 firefighters also at the moment. The fire services are saying there are no injuries.
