A massive fire that destroyed a large shopping center in Warsaw last year was the result of arson ordered by Russian intelligence services, Polish officials said Sunday on the eve of the one-year anniversary of the blaze.

Polish Foreign Minister Radek Sikorski says is ordering the closure of Russia’s consulate in the southern city of Krakow after Polish authorities said Russia was responsible for a fire that destroyed a shopping center in Warsaw last year.

Poland has accused Russian intelligence services of orchestrating a massive fire that nearly completely destroyed a shopping centre in the capital Warsaw last year. In a post on X, Prime Minister Donald Tusk said Poland knows "for sure" that the blaze at the Marywilska shopping centre was caused by arson ordered by the Russian special services.
