According to the first elements of the investigation, a firecracker could be at the origin of the explosion which occured late on Thursday morning, according to French newspaper Le Figaro.
Several people were evacuated "as a precautionary measure," according to le Fiagro, and the Parisian judicial police opened an investigation.
A police intervention is currently underway near the World Bank, which is located in the same offices as the IMF.
