Ukraine reportedly hit a Russian oil refinery and targeted Moscow during an attack involving a wave of at least 100 drones, one of the largest single operations of its kind during the war. Video footage verified by the BBC shows a fireball rising over the refinery and pumping station in the Ryazan region, southeast of Moscow, which Ukrainian officials said was a target. Russia said it had shot down 121 drones that had targeted 13 regions, including Ryazan and Moscow, but reported no damage. Elsewhere, Ukrainian authorities said three people were killed and one was injured when a Russian drone hit a residential building in the Kyiv region. Andriy Kovalenko, head of Ukraine's centre for countering disinformation, said on Telegram that an oil refinery in Ryazan had been hit, as well as the Kremniy plant in Bryansk. Kyiv says the facility produces components for missiles and other weapons. Bloggers on the social media site Telegram posted images and videos of fires raging in Ryazan. Footage verified as genuine by the BBC shows people fleeing from the site in cars as a blaze takes hold. Russian state-owned news agency RIA cited a statement from the Kremniy plant in Bryansk, which said work had been suspended after an attack involving six drones. Pavel Malkov, the regional governor, said emergency services were responding. The Kremlin acknowledged the attacks but made no mention of damage or casualties. It claimed to have destroyed 121 Ukrainian drones, including six over the Moscow region, 20 in the Ryazan region, and a number over the border region of Bryansk. Sergei Sobyanin, Moscow's mayor, said the city's air defences had intercepted attacks by Ukrainian drones at four locations. He said air defences southeast of the capital in Kolomna and Ramenskoye had also repelled drones, without specifying how many. He said there was no damage. Russian news agencies quoted Rosaviatsiya, the federal aviation agency, as saying two Moscow airports, Vnukovo and Domodedovo, had resumed flights after suspending operations for a time. Six flights were redirected to other airports. In the city of Kursk, Mayor Igor Kutsak said overnight attacks had damaged power lines and cut off electricity to one district. In Ukraine, officials said that its air defences had destroyed 25 of 58 drones launched overnight by Russia. The interior ministry said debris from one of the drones had killed two men and a woman in Hlevakha, Kyiv region, and that another person had been injured. — BBC
