Ukraine launched a mass drone strike targeting various locations in Russia, including the Tuapse oil refinery, as heavy fighting continues around the logistics hub of Pokrovsk. This follows a series of retaliatory drone and missile strikes by Russia, which targeted Ukrainian infrastructure, including energy facilities in Sumy and Mykolaiv regions. Both nations reported downing a significant number of each other's drones, with Ukraine claiming to have shot down 35 of 39 Russian drones, and Russia asserting the destruction of 75 Ukrainian drones. Amid these attacks, Russia has introduced a new anti-drone system named 'Leshyy' to counter Ukraine's aerial assaults on its oil sites. The conflict has led to severe damage on both sides, affecting energy supplies and causing civilian casualties.
