Sablanka apologized for the breakdown during the lost match with Svitolina: "My words were not addressed to Alina."
Television footage of Friday's contest showed a Belarusian woman uttering obscenities. Viewers assumed the insults were directed at Svitolina or the Ukrainians.
Sablanka claims that she had nothing personal against her opponent and cursed for another reason.
"I was angry at a small group of spectators who were aggressively celebrating my mistakes, and at that moment I reacted emotionally. However, I should have handled my frustration differently, and I apologize to anyone I may have offended. Alina played a great game and I wish her all the best in the rest of the tournament," wrote the social network.
After the match, Svitolina did not shake Sablanka's hand, following her principle of not shaking hands with rivals Russia and Belarus after the outbreak of war.
