The Russian military said it had control of Kherson, and local Ukrainian officials confirmed that forces have taken over local government headquarters in the Black Sea port of 280,000, making it the first major city to fall since the invasion began a week ago. Elsewhere, the Russians pressed their offensive on multiple fronts, though a column of tanks and other vehicles has apparently been stalled for days outside the capital of Kyiv. Heavy fighting continued Thursday on the outskirts of another strategic port city on the Azov Sea, Mariupol, plunging it into darkness, isolation and fear. Electricity and phone connections are largely down, and homes and shops are facing food and water shortages. Without phone connections, medics didn't know where to take the wounded. In just seven days of fighting, more than 2% of Ukraine’s population has been forced out of the country, according to the tally the U.N. refugee agency released to The Associated Press.
