Russia launched more than 1,600 drones and missiles over a 30-hour period, marking the most intense aerial attack since the beginning of the full-scale war in 2022.

Ukrainian drones smashed into another Russian refinery overnight, starting a fire that produced huge clouds of black smoke, President Volodymyr Zelenskyy said Thursday, in what appeared to be the latest long-range attack on Moscow’s vital oil industry.

May 21 (Reuters) - Ukrainian drones struck Russia's Rosneft-owned Syzran oil ​refinery in Samara region overnight, Ukrainian ‌military and President Volodymyr Zelenskiy said on Thursday.

"Following the president's instruction, we are now focused on creating cheap missiles to shoot down Shahed drones. We have already found solutions that are close to ready and have begun testing them."

Russia says "nuclear munitions" sent to Belarus for joint drills in the country that Moscow used as a launchpad for its 2022 invasion of Ukraine.

Russia has delivered nuclear munitions ‌to field storage facilities in Belarus as part of major nuclear drills amid tensions with European NATO members sparked by drone incursions in the Baltic.
