Kraków terror attack: six dead on the square; three more bodies found at gunman's home; national mourning declared

Six people — four women and two men — were killed and 15 wounded after a gunman drove into Kraków's Main Market Square on Saturday afternoon and fired at random from a car, Polish police and AP report. Two police officers are among the wounded; Interior Minister Marcin Kierwiński said one was shot three times and is in very serious condition and in surgery.

Małopolska police said the attack began around 3 p.m. local time. Officers exchanged fire with the suspect a short distance from the square, near Stradomska and Dietla streets, and he was taken to a hospital in custody. Police say the attacker is a Polish citizen and acted alone, and they formally denied earlier reports of a second attacker and of an officer's death. Polish media report he is 25 and wore military-style clothing; police said he used a military-type long gun and that more weapons and ammunition were found in his car.

Prime Minister Donald Tusk praised the "heroic" officers and is heading to Kraków for a briefing with ministers and security services. Motive remains unknown. This story is still developing.

Update, Nov. 7: Poland's defense minister called the attack an "act of terror," and Interior Minister Marcin Kierwiński said the 25-year-old Polish gunman may have been "fascinated with far-right ideologies." The wounded count rose to 16. Kierwiński said the suspect acted alone and was shot by police within about three minutes of the first emergency calls. He remains hospitalized in serious condition. President Karol Nawrocki has started the procedure to declare two days of national mourning.

Update, Saturday evening: Prime Minister Donald Tusk said three more bodies — two women and one man, believed to be close family of the suspect — were found at the gunman's home. President Karol Nawrocki signed a decree for two days of national mourning (Sunday and Monday). Polish officials earlier called the Main Square shooting an act of terror; the wounded count stands at about 16.

Update, Saturday night: Prime Minister Donald Tusk named the two officers who stopped the gunman as senior constables Jakub Kulik and Artur Moranski, calling them "true heroes" who likely saved many lives. Both are in serious condition after surgery; Kulik was shot three times, and a blood-donation appeal has gone out for him. Poland's police chief said officers exchanged fire with the attacker three minutes after the first reports.

Update, Saturday night: Poland's Interior Ministry said the wounded included citizens of Austria, Germany, Portugal, Russia and the United Kingdom, and that a British national was among the dead.
