Russia says Ukraine targeted chemical sites, record drone wave disrupts Moscow flights

Russia claims Ukraine attempted drone attacks on chemical facilities storing hazardous substances, but says strikes were intercepted. A Ukrainian drone hit a residential building in Tver, injuring seven; Russian air defences reportedly downed 287 drones overnight. Drone attacks caused temporary airport closures in Moscow, affecting around 200 flights; a fire broke out near the Acron fertiliser plant in Veliky Novgorod.
