The Paris prosecutor's office has said it is too early to establish the cause of Wednesday afternoon's blast, which destroyed the facade of a building housing the Paris American Academy design school popular with foreign students. At least 37 people were injured in the explosion, four of whom are fighting for their lives in hospital. Paris police and the Paris city council did not immediately reply to a Reuters request for comment. Florence Berthout, mayor of the Paris district where the blast occurred, said the 12 students who should have been in the design school's classrooms when the blast occurred had fortunately gone to visit an exhibition with their teacher.
