SLOVIANSK, Ukraine (AP) — The governor of Ukraine’s Luhansk region says Russia is mounting an all-out assault on the last Ukrainian stronghold in the eastern region, “pouring fire” from the ground and air. It comes as Western leaders meet in Germany to discuss ways of bolstering support for Kyiv. Luhansk Gov. Serhiy Haidai said Russian forces are pummeling Lysychansk after capturing the neighboring city of Sievierodonetsk in recent days. The mayor of the city of Sloviansk, to the west, accused Russian forces of firing cluster munitions that hit a residential area, killing at least one man.
