KRAKOW - A gunman in military fatigues opened fire in Krakow, Poland's second largest city, killing at least six people, according to BBC News. The BBC's report is framed as an account of what is known so far, and its headline refers to the "Krakow mass shooting."

ABC News reported that a prosecutor has said the deadly mass shooting in Poland is being investigated as a terror act. The outlet's headline attributes that characterization to the prosecutor, not to the outlet itself.

ABC News also reported that police said the alleged attacker's father, mother and sister were found dead. The summary of that report does not say where they were found, how they died, or whether their deaths are connected to the shooting.

The two reports differ in scope. BBC News gave a death toll of "at least six," while the ABC News summary does not state a toll. The available summaries do not name the alleged attacker, and neither summary describes the course of the attack in detail.

Information in this report is limited to the headlines and summaries of the two source reports. Neither summary provides further details on the victims, the attacker's motive, or the response by authorities beyond what is described above.
