President Volodymyr Zelenskyy said instead of an agreement on humanitarian corridors, what Ukraine got on Monday was 'Russian tanks, Russian Grad rockets, Russian mines.' 'They even mined the roads that were the agreed routes for taking food and medicine to the people, to the children, of Mariupol,' Zelenskyy said in what has become a daily video address close to midnight. On Monday night he spoke from behind the ornate desk in his official office, visual proof that he remains in Kyiv.
