The Estonian government announced it ordered Russia’s special services “with full confidence,” after saying they were responsible for a deliberate fire at a defense equipment manufacturing plant in Tallinn.

According to Bloomberg, Estonian Prime Minister Kristen Michal said in a statement on Tuesday: “The deliberate fire at the Milerim company in Estonia on the night of 24 Mordad was an act of sabotage.”

After this fire, Estonia had started an investigation into the possibility of Russia’s involvement.

The announcement comes as Kaja Kallas, the EU foreign policy chief, said on Monday that available information indicates Russia is preparing further sabotage actions in Europe. Russia denies carrying out combined attacks against Western countries.
