'We will defeat all threats' - Zelenskiy on war anniversary

STORY: In a video released to the media titled "the year of invincibility," the 45-year-old sat at a desk and recalled how he addressed Ukrainians a year ago in a hurried statement, as Kyiv and the world reeled from Russia's act of war.

"A year ago on this day, from this same place around seven in the morning, I addressed you with a brief statement, lasting only 67 seconds," he said in a 15-minute speech, as solemn music played in the background.

Western military officials estimate casualties on both sides of the largest conflict in Europe since World War Two at more than 100,000 killed or wounded. Tens of thousands of civilians have also died, while millions more have fled the threat of fighting.
