Uncertain future for Russia's Wagner Group in Ukraine.

Yevgeny Prigozhin, the head of Russian mercenary group Wagner, warned that his fighters may be defeated in Ukraine if they don't receive more shells. The conflict between Russia and Ukraine continues to escalate, with self-detonating drones hitting the Ukrainian capital and fatal missile strikes on apartment buildings. Ukrainian drone operators have reported chaos within Russian ranks, while retired generals analyze the "battlefield math" of the conflict.
