Poland opens a terror investigation: between grief, shock and fear after the deadly shooting The European country, not accustomed to acts of violence, woke up in a state of shock this Sunday, a day after a young man "fascinated" by the ideas of the extreme right killed six people and wounded fifteen in a busy square in Krakow, the country's second largest city. In the midst of the two-day mourning, citizens began to pay their respects to the victims, while the Polish prosecutor's office announced the opening of a terrorism investigation.
