Front-line battles in Ukraine and Russia result in devastating losses for both sides.

Both Ukraine and Russia have suffered heavy losses in the ongoing front-line battles, with Ukraine making small advances in the southeastern Zaporizhia province and the eastern Donetsk province. The counteroffensive to dislodge Russian forces from occupied areas along the 1,000km front line could last a long time, according to Western analysts and military officials. Meanwhile, Russia has declined the UN's request to access the areas under its temporary military control after the destruction of the Nova Kakhovka dam on June 6.
