Russia may shift war aims as 300 reported dead in Ukraine theatre
The Donbas is the largely Russian-speaking eastern part of the country where Russian-backed separatists have been fighting Ukraine forces since 2014.
About 300 people were killed in the Russian airstrike last week on a Mariupol theatre that was being used as a shelter, Ukrainian authorities said in what would make it the war’s deadliest known attack on civilians yet.
