The intense barrage and the launch of the nuclear-capable Oreshnik missile followed reports of major progress in talks between Ukraine and its allies on how to defend the country from further Moscow aggression if a U.S.-led peace deal is struck. Russia’s Defense Ministry said Saturday that its forces used aviation, drones, missiles and artillery to strike Ukrainian energy facilities and fuel-storage depots on Friday and overnight. It did not immediately specify the targets or damage. Overnight into Saturday, Russia struck Ukraine with 121 drones and one Iskander-M ballistic missile, according to the Ukrainian air force. It said 94 drones were shot down. Is this an escalation ?
