Artillery shells rained down on a city near Europe's biggest nuclear plant and Russian missiles struck near the Black Sea port of Odesa on Sunday, as Ukraine warned of the potential for more serious attacks by Russia as the war neared its six-month anniversary.
Wednesday marks 31 years of Ukraine's independence from Soviet rule as well as half a year since the invasion and President Volodymyr Zelenskiy called for vigilance, saying Moscow could try "something particularly ugly."
