# European security and aviation threats > Developing situation record from CLSTR: https://clstr.news/situations/european-security-and-aviation-threats > Updated: 2026-11-04T20:55:26.000Z. Sources: 503. Developments: 3. European security systems have faced increasing strain from social unrest and aviation-related threats. In France, Prime Minister Sébastien Lecornu authorized partial curfews for mayors to address violent protests involving looting and the burning of public buildings. Experts have suggested these protests may follow organized patterns intended to destabilize European societies. Parallel to civil unrest, aviation security has been tested by a wave of hoax bomb threats targeting commercial flights across several countries. On November 2, a Wizz Air flight from London Luton to Sofia was diverted to Budapest after receiving a mid-air threat, prompting NATO’s Air Defense Readiness Service to issue an ALPHA alert. Disruptions expanded on November 3, affecting at least seven commercial flights, including a LOT Polish Airlines flight and an SAS flight in Poland, as well as Ryanair flights in Italy and Spain. On November 5, the wave of disruptions intensified, affecting at least 25 passenger flights. This marked the second major wave of security alerts within a single week, involving airlines such as Aer Lingus, Wizz Air, LOT Polish Airlines, Ryanair, Finnair, and Aegean Airlines. Notable incidents included an Aer Lingus flight diverting to the Évreux military airbase in France and a Finnair flight being escorted by Italian Air Force jets. In Bulgaria, three Ryanair flights were diverted, with one landing in Plovdiv. In Spain, the Guardia Civil reported receiving three bomb threats via email within a 20-minute window targeting Air Europa and Iberia flights. Authorities in France, Italy, Belgium, Czechia, and Bulgaria responded to these alerts. While Czech police assessed the credibility of threats against four planes heading to Prague as low, security protocols were strictly enforced. European officials and experts are investigating whether these incidents constitute a coordinated campaign or “hybrid warfare” intended to disrupt critical infrastructure. ## Claims - Warsaw/Modlin Airport was temporarily closed due to the bomb threat.
