Ukraine has hit a Russian chemical plant with Storm Shadow missiles, its military said on Tuesday, referring to the UK-made long-range weapon.
Calling the strike a successful hit that penetrated the Russian air defence system, Ukraine's general staff of the armed forces stated they were still assessing the outcome of the massive strike.
The Kremlin has warned the West against providing Ukraine with weapons capable of long-range attacks; however, Kyiv insists it is crucial to strike Russian facilities integral to Moscow's war efforts against Ukraine.
According to the Ukrainian military, The Bryansk Chemical Plant is a key facility of the aggressor state's military-industrial complex.
The facility reportedly produces gunpowder, explosives, and rocket fuel components used in munitions and missiles deployed against Ukrainian territory.
Moscow has yet to comment on the attack.
This strike coincided with vows from UK Prime Minister Sir Keir Starmer and other European leaders to ramp up the pressure on Russia's economy and its defence industry until Russian leader Vladimir Putin is willing to negotiate peace.
A joint statement from leaders of Ukraine, Germany, France, Italy, Poland, Denmark, Finland, the EU, and Norway emphasized that Ukraine must be in the strongest position - before, during, and after any ceasefire.
In a related context, Russia carried out an overnight air assault on Kyiv, where Mayor Vitali Klitschko reported explosions attributed to air defence operations.
The latest developments follow a meeting at the White House last week between US President Donald Trump and Ukraine's President Volodymyr Zelensky, during which Trump indicated reluctance to supply requested Tomahawk cruise missiles.
Russia continues to control about 20% of Ukrainian territory amid its full-scale invasion initiated in February 2022.
