White House: Ultimately, Russia is responsible for tragic incident in Poland

The United States has not seen anything that contradicts Poland's preliminary assessment that a missile that landed within its borders on Tuesday was most likely the result of a Ukrainian air defense missile, US National Security Council spokesperson Adrienne Watson said on Wednesday.

"Whatever the final conclusions may be, it is clear that the party ultimately responsible for this tragic incident is Russia, which launched a barrage of missiles on Ukraine specifically intended to target civilian infrastructure." 

Key quotes

• US sees nothing that contradicts Polish president's preliminary assessment explosion was most likely the result of a Ukrainian air defense missile.
• US spokesperson says whatever final conclusions may be, it is clear Russia is ultimately responsible 
• Ukraine has every right to defend itself.

The comments follow Poland's investigation into Tuesday's news that at least two people died after Russian missiles landed in NATO state Poland on the Ukraine border. The event weighed on risk appetite on Wall Street and at the start of the day in Asia on Wednesday.
