Footage posted on social media overnight shows a series of large explosions in the Belgorod region of western Russia. Russian officials later confirmed that six rockets had hit the warehouse in Krasny Oktyabr, a city southeast of Belgorod. No casualties were reported, although Russian media reported that four soldiers were injured. The attack came as Ukrainian forces led invading troops back to the border in a series of counterattacks near Sumy, in the northeast of the country. Ukrainian defense analysts say 13 Russian tank regiments have been defeated in battles to secure key roads in the region.
