Russia-Ukraine war: List of key events, day 286

A third Russian airfield is ablaze from a drone attack, a day after Ukraine demonstrated an apparent new ability to penetrate hundreds of kilometres deep into Russian airspace with attacks on two Russian air bases. A drone struck an airfield in the Russian region of Kursk bordering Ukraine, setting fire to an oil storage tank. Russia said three of its military personnel were killed in what it said were Ukrainian drone attacks on two Russian air bases hundreds of kilometres from the frontlines in Ukraine. Kyiv did not directly claim responsibility. Ukraine's military intelligence chief said Russia had enough high-precision missiles to conduct several more big air raids on Ukraine before it runs out of stock.
