Ukraine resumed drone attacks on Russia on Wednesday, just hours after CIA Director John Ratcliffe departed Moscow following an unannounced meeting with Russian intelligence officials. Following Ratcliffe’s visit, a wave of Ukrainian strikes killed 12 people inside Russia and in the Russian-occupied Donbas region of Ukraine.

Meanwhile, Russia’s military targeted nine Ukrainian cities overnight, with officials in Ukraine reporting hundreds of ballistic missile and drone attacks. The barrage damaged residential blocks, a school and a medical facility in Kyiv and killed a 78-year-old woman in Zaporizhzhia.

The attacks came as Russia’s Foreign Ministry has warned it could target British military assets, after the U.K. supplied Ukraine with long-range missile technology.

Maria Zakharova: “We have repeatedly warned that the response to Ukrainian strikes using British weapons on Russian territory could target any British military facilities and equipment, whether in Ukraine or beyond. Those responsible for war crimes, including those committed against our country’s civilian population, will be punished in accordance with their actions.”
