Team USA's Oksana Masters and Kendall Gretsch add to Paralympics medal haul

• Masters has won five medals at the Games, while Gretsch has picked up three.
• Team China's Yilian Shan earned bronze in the women's sitting 12.5km biathlon event.

Earlier this week, Masters reflected on the difficulty of competing amid Russia's ongoing invasion of her birthplace, Ukraine.

• "I feel selfish, helpless, and guilty for being here," she wrote in an Instagram post. "However, I have always been so proud to be Ukrainian, felt so much pride at the sight of the Ukrainian flag, and now more than ever, I am the proudest to say I am Ukrainian. My mom always said my Ukrainian heart made me resilient; it made me a fighter."
• Masters was born in Ukraine with defects to her limbs and some organs linked to the nearby Chernobyl nuclear disaster. She had both of her legs amputated above the knee as a child and spent time in an orphanage before being adopted by an American woman, Axios' Rebecca Falconer writes.
