What are the odds of him posting on this thread, I wonder?
Another "separatist" leader in Lugahsnk recently resigned due to an injury, except he did it on video.
If Strelkov was okay, and heard reports that he was badly injured and in "critical condition," but needed to resign for some other reason, then he'd have done a conference too, which hasn't happened yet. If none come within the next few days, Strelkov likely either got shot by a Ukrainian or shanked by a FSB agent.
