Ukrainian forces launched a missile strike on Thursday against a Russian missile unit near Klintsy, a town in Russia’s Bryansk region, according to the General Staff of Ukraine’s Armed Forces. 

In a Telegram post, the General Staff said Ukrainian forces struck the missile launchers while Russia’s 26th Missile Brigade was preparing to fire on Ukrainian territory. 

The strike was carried out by the Ukrainian Armed Forces in coordination with the Security Service of Ukraine (SBU). 

According to the General Staff, the attack destroyed one Iskander missile launcher and damaged two others. While the results are still being verified, video footage confirmed a missile fuel detonation.

Earlier today, Ukrainian forces from the SBU reportedly scored another major operational achievement, successfully striking a loaded and ready to launch Russian Iskander ballistic missile unit in Bryansk Oblast.

“Thanks to effective reconnaissance and the coordinated efforts of the Armed Forces and the Security Service of Ukraine, the targets were successfully hit,” the General Staff stated. No civilian casualties were reported. 

The Iskander is a short-range ballistic missile system with a range of up to 500 kilometers. It can carry conventional or nuclear warheads and is one of Russia’s main tactical missile systems. 

The strike followed increased Russian activity in Ukraine’s northeast. On Tuesday, Russian forces hit downtown Sumy with rocket artillery, killing four people and injuring 28. The attack also damaged homes, a medical center, and set cars on fire. 

Ivan Shevtsov, a spokesman for the Ukrainian military in the area said Russian forces have been advancing in the Sumy region and have reportedly taken control of a stretch of territory approximately 15 kilometers along the frontline and 6 to 7 kilometers deep.
