The mighty bang heard in Paris on Wednesday was the sound of an airplane breaking the sound barrier, French police said on Twitter on Wednesday.
The police urged the population to stop calling emergency services regarding the noise in order to avoid occupying the telephone lines.
According to a Defence Ministry spokesperson, the sound heard all over Paris on Wednesday was caused by a Rafale fighter attending to another aircraft in need. The jet had been authorised to break the sound barrier, the spokesperson added.
Earlier, Twitter users from Paris reported hearing a major "blast" in the capital, audible all over the city and its environs.
The sound of the "blast" was caught on video during the Stan Wawrinka vs Dominik Koepfer tennis match in the second round of the 2020 French Open. In the video, Koepfer is seen cutting short his serve and looking up after hearing the noise.
