This was reported on Facebook by the Security Service of Ukraine (SBU) press service.
"In response to every Russian "retaliatory missile strike", we will strike back with real retribution - to destroy the invaders, their bases and equipment! We will continue to work until the complete Victory!" the statement reads.
At night and in the morning of March 9, Russia launched a massive attack on Ukraine with missiles and kamikaze drones, killing and injuring civilians and damaging critical infrastructure.
The Russian Defense Ministry called the missile attack on Ukraine a "massive retaliation" for Briansk.
Earlier, the Russian Federation reported a "Ukrainian subversive group" in the Briansk region, shooting and allegedly taking hostages. Ukrainian intelligence called the events in the Briansk region "an internal confrontation between Russian citizens."
On March 5, the KRAKEN special forces unit showed how they used a kamikaze drone to destroy an autonomous Grenadier surveillance tower in the Briansk region.
