Ukraine’s military has struck a Russian Karakurt-class small missile carrier on the Caspian Sea off Russia’s distant Dagestan region, the Ukrainian general staff said on Thursday. The port of Kaspiysk where the ship was reportedly located is more than 1,500km from Kyiv – and closer to Tehran, the Iranian capital. The extent of the damage was being assessed, the Ukrainian general staff posted online. Among its armaments, the Karakurt class can fire Kalibr cruise missiles which Moscow has used to hit civilian targets in Ukraine.

Voldoymyr Zelenskyy, the Ukrainian president, expressed satisfaction at the long-range attack and the second assault in eight days on a Lukoil-owned refinery in Perm, near the Ural Mountains. “In a mirror response to Russian strikes, we will continue our long-range sanctions. And in response to Russia’s willingness to move toward diplomacy, we will proceed along the path of diplomacy,” Zelenskyy said.
