The Russians have also lost 4,228 tanks, 8,249 armored combat vehicles and 4,911 artillery systems during their military campaign in Ukraine, the General Staff of the Armed Forces of Ukraine said on Friday, as cited by state news agency Ukrinform.
On Thursday alone, Ukrainian forces killed 640 Russian soldiers, according to the ukrinform.net website.
Other Russian losses in Ukraine include 704 multiple launch rocket systems, 466 air defense systems, 315 warplanes, 311 helicopters, 18 warships, and 4,104 unmanned aerial vehicles, ukrinform.net reported.
A top British military official said last month that "Russia has lost nearly half the combat effectiveness of its army" since invading Ukraine in February last year.
Russia invaded Ukraine on February 24, 2022, launching the largest military campaign in Europe since World War II.
