(Reuters) – Ukrainian President Volodymyr Zelenskiy, speaking in a video address released early on Wednesday, said the situation on the front line with Russian forces clearly showed the initiative belonged to Ukraine. Zelenskiy made his comments a day after Russian-installed leaders in occupied areas of four Ukrainian regions set out plans for referendums on joining Russia, a move that could sharply escalate the war.
