Despite the changes in warfare, Russian forces retain the ascendancy and are making slow but steady advances in the east and north of Ukraine. Russia has also caught up in UAV technology after falling behind early in the war, according to military analysts, and like its enemy is churning out drones domestically at a rate of millions a year.

Russia launched 400 Shahed and decoy drones, as well as one ballistic missile, during the night, the Ukrainian air force said. The strikes targeted northeastern Kharkiv, which is Ukraine’s second-largest city, President Volodymyr Zelenskyy’s hometown of Kryvyi Rih in central Ukraine, Vinnytsia in the west and Odesa in the south.

Russia continued its strategy of grinding down Ukraine with drone and missile strikes, despite Trump's 50-day ultimatum.

Ukraine’s prime minister has announced his resignation. The move possibly marks the start of a major government reshuffle.

Ukraine will get its first new prime minister of the war on Thursday, as President Volodymyr Zelenskiy tries to wrestle wartime defence spending into shape and win over both Donald Trump and a war-weary public with fresh-faced leadership.

Ukraine's prime minister announced his resignation Tuesday in the first formal step of what is expected to be a significant reshuffle of President Volodymyr Zelenskyy's government, which could also see the country's ambassador to Washington replaced.
