"An envelope exploded after it was opened and one person was slightly injured in the offices of the IMF," one police source told Reuters.

The incident, just six weeks before a presidential election, comes as a militant Greek group Conspiracy of Fire Cells claimed responsibility for a parcel bomb mailed to German Finance Minister Wolfgang Schaeuble on Wednesday.
