Russia-Ukraine war: List of key events, day 316

Heavy fighting around the largely ruined Ukrainian-held city of Bakhmut is likely to persist for the foreseeable future, according to a senior US administration official. Putin has sent a warship towards the Atlantic and Indian oceans armed with new hypersonic Zircon cruise missiles, which he said were unique worldwide. The Ukrainian foreign minister says that Patriot air defence systems being sent by the United States are expected to be deployed in Ukraine soon. Russia says that mass production of new electronic warfare and unmanned aerial vehicle (UAV) systems will start in the next few months. Ukraine says Russia had launched seven missile strikes, 18 air raids and more than 85 attacks from multiple-launch rocket systems in the past 24 hours on three cities – Kramatorsk, Zaporizhzhia and Kherson.
