Mila Kunis paid tribute to the “strength and dignity” of Ukrainian people at the Oscars as the ceremony held a moment of silence.
The actress, 38, said the world was “in awe” of the country’s resolve as it continues to repel Russian forces.
Kunis, who was born in Ukraine, has raised more than $35 million to help refugees fleeing Vladimir Putin’s invasion. Thousands of civilians have died since the war began on February 24.
She said: “Recent global events have left us feeling gutted yet when you witness the strength and dignity of those facing such devastation it's impossible not to be moved by their resilience.
"One cannot help but be in awe of those who find strength to keep fighting through unimaginable darkness."
Her tribute came moments after the ceremony held a minute’s silence for the Ukrainian people, with slides appearing on screen urging people to “Stand with Ukraine”.
They read: “We’d like to have a moment of silence to show our support for the people of Ukraine currently facing invasion, conflict and prejudice within their borders.
“While film is an important avenue for us to express our humanity in times of conflict, the reality is millions of families in Ukraine need food, medical care, clean water and emergency services.
"Resources are scarce, and we, collectively as a global community, can do more.
"We ask you to support Ukraine in any way you are able #standwithukraine."
Last week, Ukrainian president Volodymyr Zelensky revealed that he had spoken with Kunis and her husband and actor Ashton Kutcher.
He tweeted an image of himself speaking to the pair via videolink, writing in the caption: “Ashton Kutcher and Mila Kunis were among the first to respond to our grief.”
Actor Sean Penn had openly campaigned for Mr Zelensky — a former actor — to speak at the ceremony.
Meanwhile, some arrived at the ceremony wearing blue-and-gold ribbons – the colours of the Ukrainian flag.
