A major blaze erupted in the centre of the French capital on Saturday morning, in a building on the Boulevard des Capucines, authorities said, APA reports citing Sputnik.
"Firemen are intervening, avoid the area", the Prefecture de Police said in a statement on Twitter.
The fire was spotted in offices on Boulevard des Capucines 17, just in front of the Paris Opera and the Café de la Paix. At least 100 firefighters were mobilised, and they've already managed to put out the blaze, reports suggest.
Several videos purportedly from the site of the incident have since appeared online, depicting thick smoke and flames, raging in the building.
