Putin warns third parties against creating Ukraine no-fly zone

President Vladimir Putin has warned that Russia would consider any third-party declaration of a no-fly zone over Ukraine as participation in the war there, while Ukrainian officials blamed Russian shelling for breaching a ceasefire arranged in two cities to evacuate civilians.

The struggle to enforce the ceasefire in Mariupol, a strategic port in the south east, and the eastern city of Volnovakha, showed the fragility of efforts to stop fighting across Ukraine, as the number of people fleeing the country reached 1.4 million just 10 days after Russian forces invaded.
