Ukrainian President Volodymyr Zelenskyy has urged the nation to unite in his address ahead of the New Year. Russian forces continued their attacks on New Year's Eve.

Zelenskyy called on people to let 2023 be the year of return -- the return of land, soldiers, prisoners of war and normal life. He added that Ukraine is ready to fight to achieve that goal.

The mayor of the Ukrainian capital Kyiv, Vitali Klitschko, said on social media that strikes on Saturday killed one person and injured 20 others, including a Japanese journalist.

The Japanese newspaper Asahi Shimbun said one of its journalists, Sekita Wataru, was injured outside the hotel where he was staying. Sekita is reported to have sustained a minor leg injury.

Local media reported that people were also injured in the southern regions of Zaporizhzhia and Mykolaiv.

Ukrainian Foreign Minister Dmytro Kuleba condemned the attacks. He wrote on Twitter, "Russia's mass missile attack is deliberately targeting residential areas." He said Russian President Vladimir "celebrates" New Year by killing people.

Putin said on Saturday that the country must fight and move forward. He made the remark while visiting the headquarters of the southern Russian region of Rostov, which borders Ukraine.
