Ukraine launches counteroffensive against Russia amidst flood evacuations.

Ukraine's counteroffensive against Russian forces in southeast Ukraine has met with stiff resistance, with no significant gains reported so far. Meanwhile, a humanitarian crisis is unfolding in the southern region of Kherson, where biblical-scale floods followed the collapse of the Kakhovka dam on Tuesday. Ukrainian officials have insisted that Russia destroyed the dam by setting off an explosion at the Kakhovka hydroelectric plant. At least one person has died in the floods, and thousands of people have been evacuated.
