Romania summoned the Russian ambassador in connection with the arson of a defense plant. The Guardian. Bucharest blames Moscow for a fire at the state-run Karpil defense plant in Brasov in September. Three people are being investigated for their involvement in the incident. A day earlier, the Romanian security service confirmed that it had identified a Russian sabotage network behind the arson and other attempted attacks on international military installations or facilities used to train the Ukrainian armed forces. "Today, the Romanian Foreign Ministry summoned the Russian ambassador to express a strong protest regarding the sabotage on September 14 in Brasov. The evidence confirms Russia's responsibility for the unthinkable hybrid attack," the Romanian Foreign Ministry said in a statement. "We also condemned Russia's systematic attacks on merchant shipping in the Black Sea, which constitute a deliberate escalation that violates international law and freedom of navigation, with global consequences." Earlier today, the President of Romania condemned the incident and called it a "serious violation" of the country's sovereignty. "It should be clear: these are not isolated incidents; they are part of a deliberate and coordinated campaign aimed at sowing discord in our societies and undermining the commitment of European countries to their security and collective defense," Nikosor Dan said.
