“This is a defensive system, it does not entail escalation, it is defensive in nature,” RIA Novosti quoted Biden as saying at a press conference.

He noted that he had not discussed this topic with Ukrainian President Volodymyr Zelensky.

Earlier, US Secretary of State Anthony Blinken announced the allocation to Ukraine of an additional tranche in the amount of $1.85 billion and the Patriot air defense system.
