Ukraine trolls Russia for losing an attack submarine to a country that hardly has a navy

• A new video from Ukraine's defense ministry pokes fun at Russia for losing the Rostov-on-Don submarine.
• The video trolls Russia for losing a submarine "in a land war" to a country "without many warships."
• The Rostov-on-Don was likely damaged beyond repair in an attack on Sevastopol last week. 

Ukraine is taking a victory lap after a devastating attack on a key Black Sea port last week, trolling Russia's apparent loss of an attack submarine in a new video. 

The video, posted on X, formerly known as Twitter, by the Ministry of Defense of Ukraine, pokes fun at Russia for having "lost a submarine in a land war."
