Paris, June 21 Twenty-nine people have been injured, four of them seriously, after a large explosion in central Paris,
The blast took place in a building that housed a design school and the Catholic education system headquarters in Rue Saint-Jacques, in the fifth arrondissement of the French capital, BBC reported.
Emergency workers are searching through the wreckage of the building, with at least two reported to be missing.
According to witnesses, there was a strong smell of gas before the blast, BBC reported.
Paris prosecutor Laure Beccuau said after arriving at the scene that initial checks of camera footage suggested the explosion occurred within the building, which was next to the Val de Grace church, Le Parisien newspaper reported.
However, the authorities have said the cause of the blast has not yet been ascertained.
The building was initially engulfed by fire, but the blaze was later brought under control, said Paris Police Chief Laurent Nunez.
The area has been cordoned off and the Mayor of Paris, Anne Hidalgo, is at the scene, while Interior Minister Gerald Darmanin has warned people to avoid the area, BBC reported.
The area where the explosion took place runs south from the Latin Quarter in Paris's Left Bank area that is popular with tourists and known for its student population.
A student at Ecole des Mines on Boulevard Saint-Michel told Le Parisien: "I was in front of the Val de Grace, I heard a huge boom and I saw a ball of fire 20 or 30m high. And the building collapsed with a huge noise. I smelled gas, but took several minutes to come to my senses."
Another witness, Antoine Brouchot, told the BBC he was at home when he heard a "big explosion".
