Poland mobilized all its resources overnight, deploying fighter jets and placing air defense and radar units on high alert in response to Russian aerial activity that struck Ukrainian cities, Deputy Prime Minister Radek Sikorski stated for BBC News. This action occurred as Ukrainian drones targeted Russian oil refineries, including the Novokuybyshevsk refinery, marking the second strike on this facility during the current campaign of attacks on Russian refineries. The Novokuybyshevsk refinery has a capacity of 7.9 million tons of oil per year. Overnight, Ukrainian drones also targeted the Saratov refinery, with CyberBoroshno analysis suggesting the strike impacted the loading rack area. This wave of Ukrainian drone activity followed a night of widespread Russian missile and drone attacks across Ukraine, which resulted in dozens of injuries and three fatalities, according to Ukrainian President Volodymyr Zelenskyy. Attacks reportedly struck infrastructure, residential areas, and civilian enterprises in regions including Dnipro, Mykolaiv, Chernihiv, Zaporizhzhia, Poltava, Kyiv, Odesa, Sumy, and Kharkiv. Deputy Prime Minister Sikorski commented on the escalation, noting that Ukraine experienced a significant wave of disinformation during the period of Russian drone incursions into its airspace. He emphasized the need for a multi-level reaction to Russian escalation. The previous reporting period, from 6:34 AM to 7:34 AM UTC on September 20th, also captured social media imagery of the aftermath of strikes in Dnipro and a video of a UAV striking the Saratov refinery.
