KYIV, Ukraine (AP) — Ukraine’s president pledged to push for victory in 2023 as he and other Ukrainians on Friday marked the somber first anniversary of the Russian invasion that changed their lives.

As dawn broke on a day of commemorations and defiance, President Volodymyr Zelenskyy tweeted that Ukrainians had proven themselves to be “invincible” in what he called “a year of pain, sorrow, faith and the unity.”

“We know that 2023 will be the year of our victory!” the tweet said.
