According to BBC Luhansk has lost all electricity and running water. I don't think it's a diversion. Luhansk will soon fall and Donetsk will be encircled. Ukraine will soon be tightening the noose around KGB Putin's gang of mass-murdering terrorists. That's why Putin is now begging for a cease-fire, but if Poroshenko were to relent now, his own people would chase him out of Kiev.
1/3rd of the entire Ukrainian Army is being destroyed piecemeal in the south.
Lugansk is holding, it isn’t encircled, and has supply access, while the UK’s can do little except indiscriminate shelling.
Sorry, but that doesn’t sound at all like “tightening the noose”.
