Half of Donbas militants are Russian citizens, - Poroshenko
The half of the militants fighting in Donbas is the Russian soldiers. Petro Poroshenko, the President of Ukraine claimed this as his press service reported.
Poroshenko noted that the number of the regular Russian troops in occupied territory of Donbas varied from 2,500 up to 10, 000 people in different periods of time.
'They have almost 50, 000 of the so-called 'Russian volunteers' who were recruited through the Russian mobilization system and sent to Donbas. They pretend they are not the regular army soldiers. But they are Russians, they are Russians by nationality, they are Russian soldiers. They use the Russian weapons and ammunition', Poroshenko noted.

If this is so, hard to say that land should be Russia's, this is just Russian interventionism as we've seen in Georgia as well and possibly other places. IMO.
