NATO chief Jens Stoltenberg says he expects the alliance to step up supplies of air-defense systems to Ukraine in the face of the Russian missile onslaught heading into the winter. Stoltenberg said on November 28 that "one of the messages" from the NATO foreign ministers meeting in Bucharest, which begins on November 29, will be the need "to further step" up the provision of more air-defense systems, ammunition, spare parts, and training. With missiles and drones targeting energy infrastructure, Russian President Vladimir Putin is trying to "use the winter as a weapon of war against Ukraine," Stoltenberg said.
