Russia’s Armed Forces have begun preparations for what Moscow described as large-scale strikes against Ukraine’s energy infrastructure, the Russian Defense Ministry said, citing what it called Ukrainian attacks on civilian infrastructure and Russia’s fuel and energy sector.

The preparations were launched “in accordance with the instructions received,” the ministry said.

According to the statement, Russian forces continued carrying out group strikes overnight against Ukrainian defense industry facilities involved in supporting the Armed Forces of Ukraine. The ministry said attack drones targeted an asbestos-cement products plant whose warehouses were allegedly used to store explosives.

Russia’s Defense Ministry has repeatedly stated that its strikes target military and energy facilities in Ukraine, as well as infrastructure used to support Ukrainian forces.
