Ukraine said on Thursday its troops were holding out against a massive onslaught of Russian artillery in the salt mining town of Soledar in the east, with drone footage showing utter devastation there and buildings reduced to smouldering husks. In a video address, Ukrainian President Volodymyr Zelenskiy thanked two Ukrainian units in Soledar which he said "are holding their positions and inflicting significant losses on the enemy." He did not give more details.
