"We do not consider these factors to change the course of the special operation," Peskov told a briefing.
Russia will continue its actions until it reaches all goals, the spokesman added.
Earlier, Volodymyr Zelensky said he appointed Oleksand Syrsky as the new commander-in-chief of the armed forces. Zelensky said that he discussed the renewal of the Ukrainian armed forces with its current Commander-in-Chief Valery Zaluzhny, and proposed him to "remain a part of the team."
