An explosion occurred on November 17, 2025, damaging a rail line in Mika, central Poland, a key logistics route supporting Ukraine. Polish Prime Minister Donald Tusk called it an unprecedented act of sabotage designed to cause catastrophe, signaling a ramp-up in Russian sabotage campaigns across Europe. In response, Poland plans to deploy up to 10,000 troops to guard critical infrastructure. European officials note increasing challenges in countering such covert sabotage, which targets vital supply and transport lines, particularly those linked to Ukraine support. Experts interpret these acts as part of Russia's hybrid warfare strategy aimed at destabilizing European countries and hindering aid to Ukraine. Although monitoring has increased, Europe's response remains fragmented due to political and operational difficulties in directly attributing and countering such sabotage operations.
