Vessel traffic into Ukrainian Black Sea ports has been fully suspended because of the threat of Russian attacks, Agrarian Policy Minister Taras Vysotskyi said on July 23, as occupied Crimea entered its third month of a deepening, Ukrainian-engineered power collapse.

Ports close

As recently as the previous day, four to five ships were still arriving in Ukrainian ports daily; that flow has now stopped entirely amid heightened Russian strike risk, Vysotskyi said, putting Ukraine's exports — including agricultural shipments — at risk and raising the prospect of upward pressure on global food prices if the suspension persists. Some shipping companies had already begun suspending stops at Ukraine's sea ports despite the high grain season, The Guardian reported on July 23, while President Volodymyr Zelenskiy warned Russia could step up attacks on vessels in the Black Sea to undermine Ukraine's grain corridor.

Crimea in the dark

Ukraine's campaign to cut Crimea off from Russia's power grid entered its third month in mid-July, and the peninsula's electricity supply is now collapsing visibly enough to be seen from space. Working with analysts at the Berlin-based satellite-analysis group Vertical52, independent outlet Meduza examined NASA night-time satellite imagery of Crimea and found total illumination had fallen to about a fifth of normal by late June, with no meaningful recovery since — and those readings predate a July 14 Ukrainian strike on the Balaklava thermal power plant, which accounts for as much as a third of Crimea's generating capacity.

Ukrainian drones began hitting Crimea in spring 2026, initially targeting fuel infrastructure before shifting to substations and power lines. Russian authorities in Sevastopol began rationing petrol by coupon in late May, and widespread outages started in mid-June. Sergey Aksyonov, the Russian-installed head of the peninsula, said some communities had gone nearly two weeks without power, with utilities in some districts now running rolling blackouts on a three-hours-on, three-hours-off schedule.

The outages have upended daily life: card payments are failing, food is spoiling in refrigerators, and water and sewage systems are breaking down alongside the power supply. Some mobile towers have switched to generator power, and residents are organising group purchases of bottled water on social media, Meduza reported.

Black Sea shipping targetted

 

Russian forces attacked 28 civilian vessels in the Odesa region over the past month, killing 21 people and wounding 34, according to a social media post by Ukrainian journalist Iuliia Mendel on July 22.

Of the 28 ships targeted, 26 were foreign-flagged and only two Ukrainian, underlining the growing risk to international shipping using Ukraine's Black Sea export corridor. Moscow has relied mainly on strike drones, though rocket attacks have increased sharply in recent days.

The deadliest single strike came on July 19, when an attack on the tanker Golden Leo killed ten people — nine crew and a Ukrainian harbour pilot.

The intensifying campaign against foreign-flagged shipping is compounding pressure on Ukraine's Black Sea corridor, one of the few reliable export channels left since 2022. bne IntelliNews has separately reported that Ukrainian ports halted all vessel traffic entirely on July 23 amid the same threat (see companion story) — a sign the shipping squeeze is now closing off, not just endangering, Ukraine's sea lanes.
