Ukrainians mourn and vow to fight on, a year after Russia's invasion

Ukrainians paid tribute to their fallen loved ones on Friday and vowed to fight on to victory, while Russia said its forces were making gains in battle in the east as its invasion entered a second year with no end in sight.

President Volodymyr Zelenskiy, due to attend an online summit with U.S. President Joe Biden and other leaders from the West and Japan, hailed Ukraine's "year of invincibility". The leaders were expected to announce new sanctions against Russia.

"We have become one family. There are no more strangers among us. Ukrainians today are all fellows. Ukrainians have sheltered Ukrainians, opened their homes and hearts to those who were forced to flee the war," Zelenskiy said in a television address.

"We withstand all threats, shelling, cluster bombs, cruise missiles, kamikaze drones, blackouts and cold. We are stronger than that," he said. "We were not defeated. And we will do everything to gain victory this year!"
