White House spokesman Jen Psaki claims that NATO and Ukraine do not pose a threat to Russia.

"At no point has Russia been under threat from NATO, has Russia been under threat from Ukraine," she told ABC on Sunday.

ABC clarifies that this is how Psaki commented on the decision of Russian President Vladimir Putin to transfer the containment forces of the Russian army to a special mode of combat duty.

She also announced the readiness of the United States to send more humanitarian, economic and military assistance to Ukraine.

In response to a question about U.S. readiness to take action against Russia's energy sector, Psaki assured that all such options "are on the agenda."

Earlier on Sunday, Russian President Vladimir Putin, during a meeting with Defense Minister Sergei Shoigu and Chief of the Russian Armed Forces General Staff Valery Gerasimov, said that "top officials of leading NATO countries make aggressive statements about our country, so I order the defense minister and the chief of the General Staff to put the Russian army's deterrence forces on a special alert."
