AFGHANISTAN, June 6 - Russian and Ukrainian officials are signaling the start of the Ukrainian counteroffensive. ISW offers no assessment of these signals at this time. The Russian Ministry of Defense (MoD) claimed on June 5 that Ukrainian forces conducted a “large-scale offensive” across five sectors of the frontline in southwestern Donetsk Oblast on June 4. The Russian MoD claimed that Russian forces repelled all Ukrainian attacks and assigned Chief of the Russian General Staff Army General Valery Gerasimov to oversee the southwestern Donetsk frontline. Ukrainian Deputy Defense Minister Hanna Malyar noted on June 5 that Ukrainian forces are “transferring to offensive actions” in some unspecified areas of the front. Malyar added that Russian sources are actively spreading information about the Ukrainian counteroffensive to deflect attention from Russian losses in the Bakhmut direction. The Russian MoD’s claims that Russian forces immediately repelled Ukrainian counteroffensives are consistent with previous false Russian claims made during past counteroffensives. Ukrainian forces are likely making limited gains despite Russian denials. ISW will not attempt to assess at this time whether or not these gains are part of broader counter-offensive operations. ISW observed an increase in combat activity in different sectors of the frontline but will not speculate about the intent, weight, or focus of Ukrainian counteroffensives operations. A successful counteroffensive operation may take days, weeks, or even months before its outcome becomes fully clear, during which time Russian sources may falsely claim to have defeated it.
