A senior Russian diplomat has warned that the US and Russia are on the verge of an "open armed conflict" just two days after a suspected drone attack at the Kremlin that Moscow has blamed on Washington and Kiev.

Afghan voice agency (AVA) - Monitoring: We are working on preventing a fall of our relations with the US into the abyss of an open armed conflict," Deputy Foreign Minister Sergey Ryabkov said in a TV interview on Friday, RT reported. "We are already on the verge of this abyss."

Russia says Wednesday's drone incident was a US-backed attempt by Ukraine to assassinate President Vladimir Putin.
Slamming "Russiaphobic" policies that are pursued by Washington, the diplomat said the US should "think of its own safety."

"The anger and hatred towards Russia with which Washington acts in a situation in which it frankly should think of its own safety, is inexplicable," he said.

"No real diplomacy" regarding the Ukraine conflict is possible at the moment between the two nations because the US "has bet on further escalation," the diplomat said, pointing to Washington's "hybrid war" against Russia.

"The US has long been a direct participant in the conflict and has long been waging an open hybrid war against my nation," he noted.

Washington has denied involvement in the drone incident with John Kirby saying that the US does not encourage or enable Ukraine to strike outside its borders.

Ukrainian President Volodymyr Zelensky also said that Kiev had nothing to do with the reported overnight incident.

Ryabkov further said the US and Ukraine's claims of non-involvement in the incident were "not convincing anyone" and are reminiscent of "how they attempted to pretty much blame us for the bombing of the Nord Stream."

He stressed Russia's readiness to "use any means at its disposal" to deter threats to its security and the safety of its leadership.
