# Russia-Europe tensions escalate over hybrid attacks > Live situation record from CLSTR: https://clstr.news/situations/european-drone-security-and-hybrid-warfare-threats > Updated: 2026-09-10T19:18:51.000Z. Sources: 216. Developments: 9. Diplomatic tensions between Russia and European nations have escalated following a series of hybrid warfare incidents and political disputes. In Germany, Berlin attributed a drone and explosive attack at the Leipzig/Halle airport to Moscow, an incident involving military-grade equipment that European Commission President Ursula von der Leyen stated ‘will not be tolerated.’ Chancellor Friedrich Merz has accused Russia of orchestrating the operation, stating it was prepared for months and directly targeted Germany. The incident, which occurred in early August, involved a drone carrying 600 grams of military explosives found near Ukrainian Antonov cargo aircraft. The device failed to detonate due to a faulty detonator, narrowly avoiding a major catastrophe. On September 5, Germany formally characterized the August 4 incident as a ‘new quality of danger,’ leading to the closure of the Russian consulate in Bonn and the suspension of the Russian cultural center in Berlin. Russia has denied involvement, with President Vladimir Putin claiming evidence was fabricated and Foreign Minister Sergei Lavrov characterizing the accusations as the ‘beginning of a real war.’ The security concerns have since spread across the continent. On September 10, Portuguese Foreign Minister Paulo Rangel described Russian hybrid threats in Europe as ‘extremely unsettling,’ specifically citing the Leipzig airport drone attack. In response, the Portuguese Ministry of Foreign Affairs issued a diplomatic warning to the Russian representative in Lisbon. Portuguese officials reaffirmed their support for NATO, Ukraine, and European Union sanction packages against what Rangel termed the ‘highly dictatorial regime’ violating international law. ## Claims - The German government holds Russia responsible for an explosive drone attack at Leipzig/Halle Airport in early August.
