The missile responsible for killing two people in Poland was likely a Ukrainian missile, according to NATO.
An S-300 missile made in the Soviet Union was identified in the tragedy. According to the President of Poland, it is "Highly probable" that the missile is from Ukrainian anti-aircraft defense.
Additionally, Joe Biden has also declared that the missile was unlikely to have been unleashed from Russia.
Volodymyr Zelensky opposed, saying "I have no doubt that it was not our missile". The Kremlin also commented, saying that countries have made "baseless statements" on the cause of the incident.
