Fires are visible in multiple locations at the Kapotnya oil refinery in Moscow this morning (local time). Ukraine's Unmanned Systems Forces posted a fire emoji on X, a signal they have used before to seemingly imply responsibility without making an official claim. No official confirmation has been issued by Ukrainian or Russian authorities. The Kapotnya refinery, Moscow's largest, supplies roughly 35 to 40 percent of the capital's fuel market. It has been struck repeatedly since June 2026, including two major attacks within days of each other that damaged its primary crude processing units. Industry estimates put full repairs at up to a billion dollars, with some analysts projecting the facility may not be fully restored until 2027. The extent to which the refinery is damaged is still being assessed.
