Trump administration stays silent as $100 million Ukraine corruption scandal rocks Zelenskyy's government, prompting senior official resignations.

Ukraine is working to resume prisoner exchanges with Russia that could free 1,200 Ukrainians, President Volodymyr Zelenskyy said Sunday.

On the frontlines in Ukraine, changing weather has brought treacherous conditions – but also opportunities – for both sides.

Ukraine has arranged winter gas imports from Greece and aims to secure nearly 2 billion euros to offset losses caused by Russian strikes.

Ukraine’s General Staff claimed a strike on Rosneft PJSC’s refinery in Ryazan, one of the largest in Russia, while Moscow continued to target Ukraine’s energy system with missiles and drones ahead of winter.

Ukraine is working to resume the exchange of prisoners with Russia, hoping for the release of 1,200 Ukrainians, President Volodymyr Zelenskiy and his Security Council chief said.

Moscow’s attacks on gas supplies, the main source of warmth for most Ukrainian households, could plunge millions into the cold.

Ukraine’s top military commander says he has visited troops holding the front line in the key eastern city of Pokrovsk, which is besieged by a bigger Russian force, to coordinate operations in person.

Ukraine has been rocked by a $100 million corruption scandal that implicates current and former government officials.
