This is the second incident of an explosion during the same month.
Earlier, on September 16, a home-made bomb on a packed rush-hour commuter train in London engulfed a carriage in flames and injured 29 people but apparently failed to fully explode, in Britain’s fifth major terrorism incident this year.
