This is appalling. The OSCE is perhaps the only independent organization operating in the Donbass frontline. They are neither pro-Russia, nor pro-Kiev. Both the sides must make sure that their vehicle convoys are not attacked.
In fact, the work of this organization has a lot of questions. As Russia and Ukraine have been accusing the OSCE of inefficiency and reconnaissance activities in respect of both the warring parties. In any case, this is not a reason for murder. Think that someone will have to answer for the incident.
LoL good riddance, no rip. I don't like those stepping agency for world governance, or at least that's how i understand them.
The real question: is the cost of their deaths (loss of materials, loss of expertise, burials, insurances etc) higher than the cost of them living (salary, pension), for the tax payers?
It's a war zone where some people (russian influence or not, world domination struggle or not) fight for their independance and right to self governance, they expected candies and cheap prostitutes or what?
