Between 20,000 and 50,000 Ukrainians have lost one or more limbs since Russia invaded Ukraine in February 2022, The Wall Street Journal reported on Tuesday.

The figure is based on estimates made by prosthetics firms, doctors, and charities. The number could be higher as it takes time to register amputees after they undergo surgery, and fighting has intensified since Ukraine launched its counteroffensive in June.

The higher-end estimate of 50,000 came from the German prosthetics manufacturer Ottobock, which cited data from the government and medical partners. The estimate of 20,000 was based on data from the Kyiv-based charity Health of the Ukrainian People ICF. The charity estimates the number of serious injuries in the war is at 200,000 and says about 10% of serious injuries typically require amputations.
