Ukrainian President Volodymyr Zelenskyy has urged support for U.S. sanctions against Russia after President Donald Trump paused them. The White House decision raises fears of Ukraine's vulnerability to Russian attacks as winter approaches. Overnight, Russian strikes killed at least four people in Ukraine, while Ukrainian drones killed a woman in a Russian border region. Zelenskyy called Trump's move unfortunate but hoped sanctions can still be revived. Critics argue Trump's decision aids Russia. Meanwhile, Russia targeted Ukraine's energy infrastructure, while Ukrainian drones disrupted flights at Moscow airports.
