At least five people have been killed and about a dozen more injured in a shooting at Krakow’s Main Market Square in Poland today, according to Polish police. A gunman drove into the square, a major tourist area in the city’s historic center, and opened fire. Authorities have neutralized the shooter. Prime Minister Donald Tusk said police are investigating and that he is being updated by the interior ministry. U.S. Ambassador to Poland Tom Rose posted a statement to X saying, in part, that "America stands with Poland at this dark hour as Poland stands with her beloved citizens of Krakow. May the blessed memory of those lost today assuage the grief of those who mourn." The U.S. State Department also issued a security alert for U.S. citizens to avoid the area.
