MOSCOW: Moscow on Tuesday blamed US “toxicity and animosity” for the postponement of key arms control talks with Washington as tensions rage over the Kremlin’s offensive in Ukraine.

On Monday, Russia said the talks scheduled to take place in Cairo between November 29 and December 6 would be held “at a later date”.

The Kremlin declined to comment, but the Russian foreign ministry blamed the United States, pointing to “extremely negative” relations between the two countries.

New START — Strategic Arms Reduction Treaty — is the last agreement of its kind between the world’s two main nuclear powers.

“Across all spheres, we are seeing the highest level of toxicity and hostility from Washington,” foreign ministry spokeswoman Maria Zakharova said.

She accused Washington of unleashing a “total hybrid war” against Russia and said arms talks could not be conducted in the current circumstances. Zakharova said it was impossible to talk to Russia about “transparency and predictability” in the military sphere and at the same time help “the Kyiv regime kill our troops and civilians in Russian regions.”

The United States had said this month that it expected to meet Russia soon to discuss the possible resumption of inspections under New START. Moscow announced in August that it was suspending US inspections of its military sites under New START, saying it was responding to American obstruction of inspections by Russia.
