Ryazan oil refinery attack and strike on a drone launch site in Crimea: 5 November report

Ukraine’s Defence Forces struck the Ryazan oil refinery again, starting a fire. The Rosneft plant can process around 17–18 million tonnes of crude oil a year. It produces petrol, diesel and aviation kerosene, supplying Moscow and central Russia as well as the Russian military. Earlier attacks on the plant are listed in our tracker of strikes on Russian oil refineries.

Monitoring channels also reported a possible fire at a Wildberries warehouse in Ryazan.

On 4 November and overnight into 5 November, Ukraine’s Defence Forces struck a facility where Russian troops stored, prepared and launched attack drones near Hvardiiske in occupied Crimea. They also hit a drone depot near Melitopol and an ammunition depot near Novoazovsk. The General Staff separately reported strikes on a military supply depot and repair units in occupied territory.

Russia launches attacks on Ukrainian cities from sites in Crimea. The facility hit in this operation was used to prepare those attacks.

In an assessment published on 5 November, Ukraine’s military intelligence agency said Ukrainian strikes had put 15 of Russia’s 38 main refineries out of operation by the end of September. Another 12 plants had cut output. Combined refining volumes at the affected plants were down 55.4% compared with the start of the year. The figures reflect conditions at the end of September.
