Ukraine ramps up offensive operations against Russia with drone attacks.

Ukrainian forces are increasing offensive operations to end months of a battlefield stalemate and punch through Russian defensive lines in southeast Ukraine. Russian officials claim to have foiled at least one assault. Analysts suggest that Ukraine's strategy is to reach the Sea of Azov coast and sever the land corridor to the Crimean Peninsula, which Moscow annexed in 2014. Ukrainian Deputy Defense Minister Hanna Malyar said the military has scored gains, but it's not clear whether these operations are part of a long-awaited major offensive which has been mooted for months.
