Ukrainian troops have crossed the Dnieper in the Kherson region. On Tuesday, they bombed Tokmak, a city occupied by the Russians.

Both actions suggest Ukrainian military activity in the direction of Crimea. But it is still a little early, assure all the experts contacted by France 24."It's both the beginnings of the counter-offensive, and at the same time it's not it yet," says Sim Tack, a military analyst for Force Analysis, a conflict monitoring company.
