After months of military build-up and daring actions, Russia launched an unprecedented attack on Ukraine in late February.
Explosions shook several Ukrainian cities, including the capital Kyiv, in a broad invasion that began before dawn on February 24.
But 100 days later, the invasion was not the military success Moscow had hoped for. Most of the fighting has now shifted east after failed Russian advances in central Ukraine.
In the meantime, millions of refugees have fled from Ukraine to neighboring countries.
The United States, the European Union and other Western allies have imposed sanctions in response to Russia’s actions. Many people around the world have also rallied in support of Ukraine.
Russia had tightened its military grip on Ukraine since last year, amassing tens of thousands of troops, along with equipment and artillery, on its neighbor’s doorstep. The escalation of the years-long conflict has unleashed the biggest security crisis in Europe since the Cold War, and also sparked an intense showdown between the western powers and Moscow.
