Zelenskyy said Russia fired more than 300 drones and 37 missiles at Ukraine overnight. He accused Russia of using cluster munitions and conducting repeated strikes on the same target to hit emergency crews and engineers working to repair the grid.

Europe’s largest nuclear plant has been running on emergency diesel generators for more than three weeks after losing its last connection to the grid. This is the longest outage since Russia’s full-scale invasion began.

Emergency crews restored power to many parts of Ukraine on Friday after a Russian drone and missile attack struck energy facilities, plunging large parts of Kyiv and other areas into darkness and cutting water supplies.

Ten years after its intervention in Syria, Russia's influence in the Middle East has sharply declined as U.S.-led diplomacy takes center stage and Moscow struggles with the costs of its war in Ukraine.

The president said he wants both sides to stop where they are. Zelensky signaled openness to such a ceasefire as a starting point to talks.

Russia's Federal Security Service (FSB) said on Tuesday it had opened a criminal case against exiled Kremlin critic Mikhail Khodorkovsky, accusing him of creating a "terrorist organisation" and of plotting to violently seize power.

President Donald Trump is redoubling his efforts to end the war in Ukraine, announcing a second meeting with Russia's Vladimir Putin one day before sitting down with Ukraine's Volodymyr Zelenskyy at the White House.

Trump told Zelenskyy there's "a chance to end the war quickly" and expressed concerns about sending Ukraine long-range Tomahawk missiles.
