Elina Svitolina found it "extremely tough" to focus on competing at Wimbledon after Russian strikes killed 31 people and seriously damaged a children's hospital in her native Ukraine.

Svitolina, 29, broke down in tears during an on-court interview after she beat China's Wang Xinyu to reach the quarter-finals.

She played the match wearing a black ribbon on her white outfit, knowing there had been mass casualties from the assault on her homeland.

The 2023 Wimbledon semi-finalist is one of Ukraine's most prominent athletes and has spoken regularly about the impact of the war on her country.

After her 6-2 6-1 win, Svitolina said: "It was a good performance from my side and it's a very difficult day today for Ukrainian people."

Svitolina trailed off as she began to cry, with the Wimbledon crowd offering sympathetic support.

"It was not easy to focus on the match," Svitolina added.

"Since the morning it was very difficult to read the news and just to go on the court it's extremely tough.

"I'm happy I could play today and get a win."
