Ukrainian fighter Maryna Moroz dedicated her UFC 272 win to those suffering from a Russian invasion in her native country.
Moroz submitted her rival Mariya Agapova with an arm-triangle choke on the preliminary card of the event, extending her unbeaten run to three fights.
Agapova was warned for landing downward elbows in the opening round and she almost secured a choke of her own after taking the back of Moroz.
Moroz dominatied the second round of the fight after securing full mount and landing heavy strikes before eventually tapping out her opponent.
'Iron Lady' received a huge cheer from the Vegas crowd she proudly raised her Ukraine flag whilst walking to the octagon, with the fans also applauding her after the fight.
In her post-fight interview, Moroz thanked her teammates and addressed the war Russian president has declared on Ukraine in recent weeks.
"Thank you everyone who messaged me, supported me, because this week was hard for me," she said. "My family, we're in a bad situation, I want to cry because of this war, my country."
Many residents of Ukraine have been trapped after trying to escape the country as Russia continues a full-scale of southern cities such as Volnovakha and Mariupol.
Several Ukrainian fighters such as boxing Oleksandr Usyk and Bellator champion Yaroslav Amosov have returned to Ukraine to defend their country from Russian attacks.
Moroz, who is one of only three Ukrainian fighters on the UFC roster, sent Putin an expletive message last week when preparing for her fight.
