Poland Investigates Plot to Attack PM Tusk, Defence Minister

Polish authorities are investigating a possible plot to attack Prime Minister Donald Tusk and Defence Minister Władysław Kosiniak-Kamysz, a government spokesperson confirmed on Sunday, as the country reels from a week of deadly school stabbings. The alert, announced by Interior Ministry spokesperson Karolina Gałecka, follows three separate knife attacks that left a school caretaker dead and at least 15 people injured across the Masovian Voivodeship.

The investigation marks an escalation in a week of violence that has put the NATO and EU member state on edge ahead of winter, amid ongoing tensions over the war in Ukraine. The alleged plot, while still under investigation, has prompted crisis talks and a manhunt.

What Happened: A Week of Violence in Polish Schools

The alleged plot emerged as Poland was already on high alert following a wave of school stabbings between 7 and 10 October 2026. The attacks, which police say were not coordinated terrorism, unfolded as follows:

• 7 October – Ostrołęka: A 19-year-old student attacked nine people with a machete, injuring five students, two teachers and two bystanders before hurting himself. He also carried unused homemade explosives.
• 8 October – Leszczydół-Nowiny: A 15-year-old, reportedly wearing a camera-mounted helmet, stabbed three people and fatally wounded a 37-year-old caretaker before the principal restrained him.
• 10 October – Warsaw: A 21-year-old woman injured three people at a private school, TEB Edukacja.

Police detained 117 suspects and inspected 64,000 schools across the country. Prime Minister Tusk said the attacks were spontaneous and inspired by online activity. He pointed to a digital glorification of violence and nihilistic violence among teenagers. AP News reported that some detainees were active in ultraright environments.

The Alleged Plot and Official Response

The possible plot against Tusk and Kosiniak-Kamysz prompted an emergency meeting at the Internal Security Agency's Counter-Terrorism Centre at 11:00 a.m. on Sunday. Interior Minister Marcin Kierwiński and Special Services Coordinator Tomasz Siemoniak ordered immediate action after police received the information, Gałecka said on X. NY Post reported that a man was later arrested on suspicion of plotting an attack targeting the prime minister and senior defence officials, according to AP.

Polish security services have not released details about the suspect or the nature of the alleged plot, but the case underscores the heightened threat level facing top officials. Defence Minister Kosiniak-Kamysz is also Deputy Prime Minister, making the alleged plot a direct challenge to Poland's civilian and military leadership.

Russia Hybrid Attack Fears

Poland has been on high alert over fears of a Russian hybrid attack aimed at weakening Western support for Ukraine war. As a key NATO and EU member on the eastern flank, Poland has repeatedly warned about sabotage, disinformation and violence orchestrated by Moscow. The school stabbings, while not directly linked to Russia by officials, have fuelled public anxiety about security and online radicalisation.

Prime Minister Tusk has previously cautioned that Russia could exploit social tensions and digital platforms to destabilise Polish society. The latest threat against top officials, coming just days after the school attacks, underscores the volatile security environment as winter approaches.

Impact on Poland and European Security

The investigation into the alleged plot against Tusk and Kosiniak-Kamysz is likely to intensify scrutiny of Poland's counter-terrorism and online safety policies. President Karol Nawrocki recently vetoed parts of the Digital Services Act implementation, sparking debate over how to curb violent content online. The government is now facing pressure to accelerate measures against online glorification of violence while balancing civil liberties.

Analysts say the convergence of school violence, an alleged assassination plot and fears of Russian interference could reshape Poland's domestic security agenda ahead of parliamentary debates this winter. The European Union is also watching closely, as Poland's stability is critical for the bloc's eastern defence posture.
