"Not today or tomorrow, of course, but all depending on our reserves and supplies," the general added.Russian forces shifted their focus toward Chasiv Yar, an elevated town that potentially opens the way to further advances into the oblast, after capturing Avdiivka in February.Ukraine is also facing a difficult situation near the village of Ocheretyne, a village some 15 kilometers (nine miles) northwest of Avdiivka, where Moscow's troops have reportedly managed to create a salient. Skibitsky believes that as its first goal, Russia will seek to capture the rest of Donetsk and Luhansk oblasts.Looking further ahead, the Kremlin is likely preparing for an offensive around northeastern Sumy and Kharkiv oblasts, with the main push likely to begin at the end of May or early June, Skibitsky suggested.
