Black Sea in Flames: The Sinking of the MV Golden Leo, Ukraine’s Drone Blitz, and a Frozen Grain Corridor

Ukraine's Operation MoLoChKa

Ukraine launched Operation MoLoChKa (Ukrainian for "dairy") on July 6, 2026, a sustained naval and aerial drone campaign targeting tankers and cargo vessels of Russia's shadow fleet — ships used to evade Western oil sanctions . The operation is commanded by Robert Brovdi (call sign "Madyar") of Ukraine's Unmanned Systems Forces .

Within days, the campaign achieved staggering numbers:

• By July 13, Ukrainian drones had hit 105 Russian shadow fleet vessels over eight nights .
• Overnight on July 15, 20 more vessels were struck — 17 oil tankers, two gas tankers, and one tugboat .
• On July 17, 12 more vessels (nine dry-cargo ships, one tanker, one gas carrier, one tug) were hit .
• On July 18–19, four vessels and 13 power substations in occupied Crimea were struck .
• By July 22, the total reached 196 vessels hit since the campaign began .

The campaign effectively suspended Russia's Don River–Sea of Azov grain export route, which normally handles about a quarter of Russia's grain exports . Russian authorities stopped accepting applications for vessels to transit the Kerch Strait on July 11 after more than 100 ships operating in the Sea of Azov came under drone attacks . Russia was later expected to export 1.5 million metric tons of wheat in July, down about 30% from the previous projection .

Russian Strikes on Civilian Shipping and Port Infrastructure

In parallel, Russia escalated attacks on Ukrainian ports and civilian merchant vessels:

• July 16: Russia struck infrastructure at Odesa and Pivdennyi ports and a maritime vessel .
• July 18: A drone attack on Mykolaiv port damaged three foreign-flagged civilian vessels and killed three people .
• July 19: The Golden Leo attack occurred .
• July 22: Ukraine's grain trade authority reported that Russian strikes on civilian vessels had "virtually paralyzed maritime exports" .
• July 25: Russia struck another civilian vessel flying the flag of Palau and carrying corn near Odesa, igniting a fire .

Since 2022, Russia has damaged or destroyed 1,054 port infrastructure facilities in Ukraine, according to acting Foreign Minister Andrii Sybiha .

Disruption to Grain Exports

The attacks caused a severe disruption to Ukraine's agricultural export corridor:

• Shipowners suspended vessel calls to Ukrainian Black Sea ports for agricultural exports as of July 23 .
• Ukraine lost about one-third of its grain export capacity via the Black Sea corridor .
• No vessels were transiting the Ukrainian maritime corridor as of July 23, at the height of harvest season .

One of the world's largest container shipping companies, Maersk, also halted calls .

International Response and UN Security Council Meeting

Ukraine's acting Foreign Minister Andrii Sybiha formally requested an emergency UN Security Council meeting on July 23, citing Russian attacks on civilian shipping and the paralysis of the grain corridor .

The UN Security Council convened the emergency meeting on Monday, July 27, 2026 at 10:00 AM Eastern Time, at Ukraine's request . The meeting was supported by Council members Denmark, France, Greece, Latvia, and the UK . Briefers included officials from the UN Department of Political and Peacebuilding Affairs and the UN Office for the Coordination of Humanitarian Affairs . The agenda was Russia's shelling of civilian vessels and port infrastructure in Ukraine .
