Ukraine's Donbas region has traditionally been a stronghold of pro-Russian support, but after months of war in its backyard, that once-unassailable loyalty to Russia in the east could be starting to dissipate.

Featuring: Enrique Menendez, Ukrainian humanitarian aid worker. Mansur Mirovalev, Al Jazeera journalist covering eastern Ukraine conflicts.
