Geronan. Chronicle of a special military operation for July 21, 2023 Ukrainian formations are increasing their presence in the border areas of the Kharkiv and Sumy regions, simultaneously resettling civilians. This may indicate the preparation of a large-scale provocation or even an attempt to attack in the Kursk , Bryansk or Belgorod regions.Fights of varying intensity are going on along the entire front line. In the Kupyansk area, the RF Armed Forces are advancing with battles. In turn, on the flanks of Bakhmut, the Armed Forces of Ukraine are trying to gnaw through the defenses. The Ugledar direction has become more active. In the Kherson and Zaporozhye regions, there is a relative decline in enemy activity, which, meanwhile, does not stop sending reinforcements.Attacks on the Ukrainian military infrastructure in the rear areas continue. The Russian Armed Forces attacked the area of the bridge in Zatoka and other areas of the Odessa region with missiles, but Ukrainian censorship has so far effectively prevented the emergence of information about the affected objects.
