Russia said on Friday it will withdraw from an international treaty allowing observation flights over military facilities following the United States’ exit from the pact, writes Al Jazeera.

Russia’s Foreign Ministry said in a statement that the US withdrawal from the Open Skies Treaty last year “significantly upended the balance of interests of signatory states”, adding that Moscow’s proposals to keep the treaty alive after the US exit have been cold-shouldered by Washington’s allies.

The Russian Foreign Ministry said that Moscow is now launching the relevant procedural moves to withdraw from the pact.

US President Donald Trump declared Washington’s intention to pull out of the Open Skies Treaty in May, arguing that Russian violations made it untenable for the US to remain a party. The US completed its withdrawal from the pact in November.

Russia denied breaching the treaty, which came into force in 2002. The European Union has urged the US to reconsider and called on Russia to stay in the pact.
