Polish and other NATO jets scrambled on September 20 as Russia launched another massive drone and missile attack on Ukraine. Zelenskyy repeated calls made following the September 9 drone incursions for NATO to work with Ukraine on joint air defenses. The Ukrainian Air Force said air defenses had intercepted the vast majority of incoming fire, highlighting the use of US-made F-16 jets against Russian cruise missiles. The head of the Samara region, Vyacheslav Fyedorishchev, said four people were killed in a Ukrainian attack. The head of the Saratov region, Roman Busargin, wrote on Telegram that windows were blown out of two housing blocks and one woman was hospitalized.
