Russia is suspected of carrying out a campaign of sabotage across Europe, targeting military and defense sector sites. A series of suspicious fires broke out at facilities in Italy, Estonia, Bulgaria, and Slovakia in August, with some countries already blaming Russia for the attacks. According to the article, Germany's interior minister has declared that "Russia is responsible" for the drones found at Leipzig airport, while Poland's interior minister warns that there are "many signals" pointing to a change in Russia's strategy. The incidents have resulted in damage and arrests, with some suspects allegedly following orders from Russia.
