the ukrainian military has dropped that feeling of impotency we've seen over the last month, where nothing they did seemed to make any change. seems yesterday the separatists crossed the red line of the airport and the ukrainian government responded. but do we now today see in hand a response from the separatists themselves, an escalation on their part, or does this begin to shatter their ranks? one small indication that the latter might be the case, today the russian news agency reporting that the commander in slovyansk among separatists has ordered two of his commanders shot dead, he says for looting in that case, according to the russian media report, but that's the first sign, perhaps, of descension in the ranks here and the separatists are not necessarily communicating like they want to. interesting and intense days ahead here in a city which had thought, perhaps, it had escaped the worst of the violence during the unrest. >> interesting and intense. obviously audio issues. you can take it from here. >> i'm john, christine.
