Sea mines are documented in the 2014 Russia-Ukraine War through official intelligence releases, maritime safety advisories, and reported mine incidents in the northwestern Black Sea. In June 2022, U.S. officials told The Guardian that Russian forces were deploying mines near Ochakiv and had previously mined the Dnieper River while blockading Ukraine's remaining Black Sea ports.
Ukraine's Ministry of Foreign Affairs, in a March 2022 communication circulated by the International Maritime Organization, accused Russia of using drifting sea mines in the Black Sea after mines were found off Turkey and Romania. The Ukrainian statement said those mines were not registered with Ukraine's naval forces at the start of 2022 and linked them to stocks seized during Russia's 2014 occupation of Sevastopol.

Timeline
The mine threat emerged publicly in the first weeks of the full-scale invasion. On 29 March 2022, Ukraine reported to the IMO that drifting mines found off Turkey and Romania were part of Russian naval activity in the Black Sea. U.S. maritime guidance dated 4 September 2022 then warned of moored and drifting naval mines in many Black Sea areas, alongside reports of commercial vessels struck by projectiles or explosions near Ukrainian ports and the northwestern Black Sea.
On 23 June 2022, the U.S. intelligence account reported by The Guardian tied Russian mine deployment to the blockade of Odesa and Ochakiv and to previous mining of the Dnieper River. On 4 October 2023, the U.K. Foreign, Commonwealth & Development Office released intelligence that Russia may use sea mines against civilian shipping approaching Ukrainian ports to deter grain exports through Ukraine's humanitarian corridor.

Narrative
Mine warfare in the conflict served a maritime area-denial role. The documented locations and warnings center on Ukrainian port approaches, the northwestern Black Sea, and the Dnieper/Dnipro river system, where mines threatened warships, merchant vessels, grain shipping, fishing activity, and later mine-clearance work.
The clearest attribution for deliberate Russian use comes from U.S. and U.K. government intelligence releases and Ukraine's IMO-circulated statement. Other safety and humanitarian sources document the broader hazard without always assigning responsibility for each individual mine. The U.S. Maritime Administration warned U.S.-flagged commercial vessels that both moored and drifting mines had been reported in many Black Sea areas, and IMO described the conflict as a serious and immediate threat to vessels and crews in the Black Sea and Sea of Azov.
Mine incidents continued after Ukraine opened alternative export routes. In December 2023, the Associated Press reported that a Panama-flagged civilian cargo ship struck what Ukrainian officials described as a Russian floating mine near Ukraine's Danube ports, injuring two sailors. Greenpeace's 2024 Black Sea mine-risk report described an ongoing regional hazard, including mines drifting from the war zone and mine-clearance activity by Black Sea states.
