Figure caption, Ukraine's military has shared video of a naval drone strike on a Russian tanker Ukraine's military has intensified its attacks near Russian-annexed Crimea, following up strikes on Russia's land corridor to the peninsula by targeting maritime supply routes as well. Ukraine's drone force commander Robert Brovdi, also known as Magyar, says at least 25 ships have been hit and set on fire over the past four days in the Sea of Azov, the inland sea linked to the Black Sea by the Kerch Strait. Such losses in so short a time are a clear blow to Russia's naval capability as well as Vladimir Putin's guarantee of maintaining fuel supplies. These attacks appear to be the latest phase of Ukraine's self-declared logistics lockdown which aims to choke off supplies and routes into and out of occupied Crimea.

Footage circulating on social media appeared to show smoke rising over the Feodosia terminal. Local Russian-installed officials told RIA Novosti that efforts to extinguish the fire were ongoing. Meanwhile, the defence ministry in Moscow said that 12 Ukrainian drones were shot down over the peninsula overnight out of a total of 21 launched by Kyiv. In a statement announcing the attack, Ukraine's general staff said that oil products shipped from the terminal were being used to "meet the needs of the Russian occupation army". The facility was previously hit in a Ukrainian drone strike in March.

Drones, missiles and cross-border artillery took centre stage during the 62nd week of Russia's war in Ukraine, as the 63rd began with a dramatic allegation from Russia – that Ukraine made an attempt on President Vladimir Putin's life. Ukraine may have targeted Russian fuel depots – a possible preamble to its expected counteroffensive. Russia, meanwhile, sharply intensified strikes against Ukrainian civilians, claiming dozens of lives. Ukraine was likely responsible for explosions in Kozacha Bay, near Sevastopol on the Crimean Peninsula, where the Russian Black Sea Fleet has a base, on April 29. Footage showed a massive black mushroom cloud rising from a fuel tank park.
