Multiple reports say Ukraine carries out a large drone attack on June 12, coinciding with “Russia Day,” striking major oil refining and petrochemical facilities in Russia’s Tatarstan and Samara regions. Ukrainian monitoring channels identify targets that include the Taneco oil refinery and Nizhnekamskneftekhim, described as a major producer of synthetic rubber and related plastics. The Kyiv Post reports that fires break out at several energy and industrial sites, including the Nizhnekamskneftekhim complex and Taneco refinery. It also says the attacks disrupt Russia Day events and lead to temporary airspace restrictions in the affected regions.
On the Russian side, the Kyiv Post reports that authorities claim to have downed 231 drones overnight, reflecting an extensive air-defense response. Together, the accounts indicate coordinated strikes aimed at refineries and petrochemical operations in two regions, with immediate firefighting activity and temporary operational disruptions reported in those areas. Neither source provides independent confirmation of the claimed target lists beyond the accounts cited.
