The risk of escalating by the war in Ukraine is “rising a lot” warned US President Donald Trump’s envoy, Keith Klogg, following the attack by Ukrainian forces with drones on several Russian airways.

“I tell you, risk levels are rising a lot – I mean what happened this weekend,” he said Keith Klog, At Fox News.

“People in the field of national security must understand: When you are attacked in the part of the national survival system of an opponent, which is his trio, the nuclear trinity, it means that the level of danger is increasing because you do not know what the other side is going to do. You’re not sure, “he added.

Ukraine attacked airports in Siberia and north, Russia, at the weekend, affecting targets of up to 4,300 kilometers from the first line of the conflict.

Kogek said the damage caused to Russian bombers over the weekend was less significant than the psychological impact on Russia and that he was particularly concerned about unconfirmed reports of a Ukrainian naval attack in northern Russia.

White House spokesman Caroline Livit said on Tuesday that Trump had not been informed in advance of unmanned Ukraine attacks on Russian bombers.
