Estonia attempted to detain a Russian-flagged shadow fleet tanker in the Baltic Sea on May 15, prompting a Russian military jet to violate NATO airspace in response. The tanker was later released. This incident reflects broader EU and UK sanctions enforcement against Russia's illicit oil transport network.
