A fire engulfed a shopping centre in the Russian city of Grozny, in Chechnya, the territory controlled by Vladimir Putin's ally Ramzan Kadyrov.

       Astonishing pictures circulating on social media show the two-storey building being devoured by the blaze during the night between January 21 and 22.

       The cause of the fire is still unknown, but no casualties have been reported, according to the Russian Ministry of Emergency Situations (EMERCOM).

       A statement by the ministry read: "A two-story store caught fire in the centre of Grozny. EMERCOM of Russia firefighters prevented the flames from spreading to neighbouring buildings. No one was hurt.

       "The fire on 1,500 square meters was extinguished by 74 specialists and 10 units of EMERCOM of Russia equipment."

       This comes following a series of drone attacks launched on Russia by Ukraine.

       Volodymyr Zelensky's forces carried out a series of drone strikes against Russian defence industrial enterprises and oil refineries in Russia on the night of January 20 to 21 as part of an ongoing series of strikes aimed at crippling Putin's military capacity, the Institute for the Study of War (ISW) reports.

       Ukraine reported a strike against Rosneft's Lisinskaya Oil Refinery in Voronezh Oblast for the second time this week after an attack on the night of January 15 to 16.

       The Governor of Voronezh Oblast, Alexander Gusev, claimed on January 20 that Russian forces destroyed several drones in the region, but that one fell on an oil depot in Liskinsky Raion. This reportedly started a fire.

       A Kremlin-affiliated Russian mil-blogger noted that the oil depot was still burning from the January 15-16 strike and the second strike started another blaze.

       The ISW also reported that the Ukrainian General Staff claimed that Ukraine's Unmanned Systems Forces and SSO struck the Smolensk Aviation Plant in Smolensk Oblast.

       Astra, an independent Russian news outlet, reported that Ukrainian troops hit Lukoil's Saratovorgsintez Chemical Plant in Saratov City earlier this week. It produces acrylonitrile, acetonitrile, and sodium cyanide.

       Putin's Ministry of Defense (MoD) claimed that Russian forces destroyed 10 drones over Smolensk Oblast, six over Voronezh Oblast, and four over Saratov Oblast on the night of January 20 to 21.
