Ukraine Launches Counteroffensive Actions, Petraeus Optimistic.

Ukrainian President Volodymyr Zelensky has hinted that Ukraine's counteroffensive against Russia's occupying forces is underway, following comments by Russian President Vladimir Putin. Russia's Defense Ministry reported further Ukrainian offensive operations along the frontline, but CNN is unable to verify Russian defense ministry claims. Ukraine has stepped up military activities, including shaping and probing operations, but there is still no evidence of a major advance involving large numbers of forces.
