The Russian defence ministry in its latest update from the battleground has claimed that over 580 Ukrainian troops have been killed and units in 197 areas have been destroyed by its forces in the past day. This came as it released a new video of its MSTA-S Howitzer in combat action. The video shows the Russian drones tracking camouflaged Ukrainian strongholds and the Howitzer unleashing accurate fire on them. Meanwhile, Ukrainian President Volodymyr Zelensky has dismissed the governors of three regions including Luhansk and Odessa. On the other hand, Russia has said that the relations with the U.S. were in dire straits after the MQ-9 drone crash in Black Sea.
