Drones of the Security Service of Ukraine and the Special Operations Forces attacked several Russian facilities in Ryazan and Bryansk. Meanwhile, the Ukrainian Armed Forces have thwarted Russian plans in the Kursk region and are advancing elsewhere.

Videos showed fireballs over a facility in Ryazan, 110 miles southeast of Moscow. Kyiv is seeking to disrupt Russian military logistics and put pressure on the country’s economy by striking its oil industry.

The reported strike comes two nights after Ukrainian forces launched a joint attack against the refinery that allegedly damaged multiple on-site facilities.
