It has been almost two years since Russian forces stormed across the border into Ukraine on February 24, 2022.
In what has become a drawn-out and bloody conflict, the Ukraine-Russia war has claimed many thousands of lives, driven millions from their homes and left entire cities in ruins.
The focus has since turned to even bloodier conflict in the Middle East as Israel continues to shell occupied Palestinian territories, killing thousands of civilians.
At the same time, the military stalemate between Ukraine and Russia shows no sign of ending.
As we look toward the grim anniversary, here is a look at some of the conflict's major incidents.
