Tusk had said in March that evidence from Lithuania suggested Russia was to blame for the attack, in line with suspicions in Poland, but his statement on Sunday was unequivocal in assigning responsibility to Russia.
The Lithuanian investigation found that a May 9, 2024 arson attack on an IKEA store in Vilnius, as well as the May 12, 2024 Marywilska fire, were set by Ukrainian citizens acting on behalf of Russia, Tusk wrote in March. A week earlier, Polish prosecutors had said a Belarusian refugee was responsible.
Nobody was injured in the fire in Warsaw.
