http://dilyana.bg/us-diplomats-involved-in-trafficking-of-human-blood-and-pathogens-for-secret-military-program/I recommend reading the article, I'd end up writing a few pages just to make sure I summarised everything in it correctly.
Basically, it's an investigative report on a US base in Tbilisi, Georgia, where they run a large bio-warfare laboratory. It's wreaking havoc on the local population via waste disposal and (alleged) escaped pathogens, even causing several deaths, but the main story is that they've been abusing diplomatic carriage to transport specimens, ostensibly so that they won't have to explain themselves or submit to customs. Apparently it's a large-scale operation, and similar labs operate in many states of the former USSR - the two salient points are that these labs were chosen to be built close to Russian borders, and that work there is inextricably tied to US embassies and 'diplomatic' staff.
While the rest of the article is interesting, I think this is the most important and dangerous part ties into an article I read a while back:
https://www.rt.com/news/408416-russians-biological-samples-research/Basically, the US Air Force has been looking for and collection Russian genetic matter for a few years now, both covertly and overtly. I don't think it's a stretch to think research is likely being performed in biochemical weapons meant to target specific ethnic/racial populations, or that the response will be extreme if it's ever verified.
