KYIV—Ukrainian forces were holding their positions in intense street fighting and under day and night shelling in Sievierodonetsk, officials said, as Russia pushes to control the bombed-out city, the key to its objective of controlling eastern Ukraine.
Sievierodonetsk and its twin city Lysychansk, on the opposite bank of the Siverskyi Donets river, are the last Ukrainian-controlled parts of Luhansk Province, which Russia is determined to seize as one of its principal war objectives.
