What happened

An overnight Ukrainian drone attack damaged the Novoshakhtinsk oil refinery and halted operations, Rostov governor Yuri Slyusar said. The Associated Press reported that it was the fourth Ukrainian attempt against the refinery in the preceding year, based on Ukraine General Staff data. Authorities did not publish the damaged unit, quantify lost output or provide a restart estimate. The refinery's own corporate history says its first construction phase ran from 2004 to October 2009 and describes two 2.5-million-tonne-per-year primary-processing units; industry material describes a design capacity of up to 7.5 million tonnes per year. Its corporate product catalogue includes straight-run gasoline or naphtha, marine and other fuel oils, bitumen and sulfur, while its logistics system includes crude reception, rail facilities, river-sea tankers and a Rostov-on-Don oil terminal. These figures describe nameplate capability and product range, not verified output immediately before the attack. This is a distinct 2026 event and is not merged with the refinery's separately recorded 2022 and 2024 strikes. The supplied infographic dates the event to 23 August, but AP, Interfax and Russian regional reporting consistently date the overnight attack and shutdown to 25 August; this record therefore retains 25 August. The infographic's Rosneft ownership label is not treated as established because it conflicts with the reviewed corporate and ownership reporting.
