Zelenskiy said on Saturday that the situation on the front lines in the east of the country was getting tougher and Russia was throwing more and more troops into battle. Russian forces are slowly gaining ground in the Donbas region, encircling the city of Bakhmut north of Donetsk and battling to take control of a nearby road which is a major supply route for Ukrainian forces. They are also trying to capture Vuhledar, southwest of Donetsk.
