Andy Murray has pledged to donate his prize money for the remainder of 2022 to children affected by Russia's invasion of Ukraine.

The conflict has led to more than two million people fleeing the country over the past two weeks, according to figures released by the United Nations.

Tennis' governing bodies, the ATP, WTA, and International Tennis Federation (ITF), as well as the four grand slam organisers, announced on Tuesday that they are to donate a total of $700,000 to help humanitarian efforts in Ukraine.

Three-time major winner Murray is also doing his bit by working closely with UNICEF – the world's leading organisation helping children in danger – to provide medical supplies and development kits.

"Over 7.5m children are at risk with the escalating conflict in Ukraine," Murray posted on his personal Twitter page.

"It's vital education continues, so UNICEF is working to enable access to learning for displaced children, as well as supporting the rehabilitation of damaged schools, together with replacement equipment and furniture. 

"I'm going to be donating my earnings from my prize money for the rest of the year, but anyone in the UK can support UNICEF's humanitarian response by donating to our appeal."

Ukraine's Dayana Yastremska donated her prize money from last week's run to the Lyon Open final, where she lost in three sets to Zhang Shuai, to help her home country.
