Ukraine's Zelenskyy says Russia's 'big revenge' has begun

Russia has begun its "big revenge" for Ukraine's resistance to its invasion, Ukrainian President Volodymyr Zelenskyy has said, as Russian forces claimed a series of incremental gains in his country's east. Zelenskyy has been warning for weeks that Moscow aims to step up its assault on Ukraine after about two months of virtual stalemate along the front line that stretches across the south and east. While there was no sign of a broader new offensive on Monday, the administrator of Russian-controlled parts of Ukraine's eastern Donetsk province, Denis Pushilin, said Russian troops had secured a foothold in Vuhledar, a coal mining town whose ruins have been a Ukrainian bastion since the outset of the war. Pushilin's adviser, Yan Gagin, said fighters from Russian mercenary force Wagner had taken partial control of a supply road leading to Bakhmut, a city that has been the focus of a Russian offensive for months. A day earlier, the head of Wagner said his fighters had secured Blahodatne, a village just north of Bakhmut.
