Ukraine's Troop Movements Raise Tensions and Speculation.

Ukrainian troops have established positions on the eastern side of the Dnieper River, leading to speculation of a spring counteroffensive to break through the land corridor between Russia and the annexed Crimean Peninsula. Recent fighting has become a war of attrition, but Ukraine has received sophisticated weapons from its Western allies and new troops freshly trained in the West. The Kremlin-installed head of the Kherson region denied Ukrainian forces have established a foothold on the east bank of the Dnieper. Russian forces have launched attacks on Kharkiv and the surrounding region, causing damage but no casualties.
