The latest attack occurred early Tuesday, with explosions and active gunfire reported during the incident. Local residents noted that at least 10 drones were downed by air defense units over Tuapse.

This marks a troubling trend. The refinery processes about 12 million tons of oil annually. Previous attacks have already destroyed 24 storage tanks and damaged four more.

A state of emergency was declared in the municipal district following the third attack. Russia’s Emergency Situations Ministry claimed to have extinguished the fires just two days prior, on April 29, 2026.

Ukrainian drone attacks on Russian oil infrastructure reached a four-month high in April 2026, with at least 21 attacks recorded. This escalation has significantly reduced Russia’s average refinery capacity to 4.69 million barrels per day, the lowest since December 2009.

The environmental fallout from these attacks has made Tuapse unsafe for visitors. Residents report airborne petroleum byproducts and oil spills on city streets.

Putin has proposed a temporary truce during the May 9 holiday amid this uptick in drone strikes. However, it remains unclear if this will lead to any meaningful ceasefire agreement.

Photos and videos of the fourth attack emerged on social media shortly after it occurred, highlighting the ongoing conflict’s impact on Russian infrastructure.
