Ukraine has hit a Russian chemical plant with UK-made Storm Shadow missiles, the Ukrainian military said on Tuesday, BBC reported.

Calling the strike "a successful hit" that penetrated the Russian air defence system, Ukraine's general staff of the armed forces said they were still assessing the outcome of the "massive combined missile and air strike".

The Kremlin has been warning the West not to give Ukraine weapons capable of long-range attacks, but Kyiv says it's imperative to target Russian facilities that play a key role in Moscow's war against Ukraine.

"The Bryansk Chemical Plant is a key facility of the aggressor state's military-industrial complex", the Ukrainian military said in an X post on Tuesday, according to BBC.
