This was reported by the Ukrainian military of the 24th Special Operations Brigade "Aidar" Stanislav Bunyatov.
According to him, at night they carried out powerful artillery preparation, and DRG groups tried to probe the border line. They were repulsed.
“The situation is very tense. The main reserves are expected to be brought in in the near future; they must fight back,” the fighter writes.
Russian military public pages also write that from 5 am they intensively shelled the Kharkiv region, especially Vovchansk.
The Kharkiv RMA sparingly writes that 21 settlements, in particular Vovchansk, were subjected to artillery and mortar strikes by the Russian Federation.
