Ukrainian Deputy Prime Minister Iryna Vereshchuk announced Thursday that the first full-fledged prisoner swap deal with since the Russian invasion has freed 29 Ukrainian military personnel and civilians in exchange for 21 Russian military personnel and civilian sailors, NPR reports. It is unclear if the famously defiant “Russian warship, go fuck yourself” soldiers of Snake Island were among those freed, but Ukraine’s border agency had specifically stated earlier Thursday that Vereshchuk was working to secure their release. The 19 civilian sailors released are the crew of a ship captured as they attempted to evacuate the soldiers from Snake Island in late February.
