UN agencies kicked out of separatist held eastern Ukraine....but why?

What is not reported is why the UN agencies were told to leave.

U.N. Agencies Told to Leave East Ukraine

The timing is odd because the agencies have been told to leave just as hostilities have quieted down, so there would seem to be no security issue.

It is possible as some have reported that it is because the separatists distrust the UN agencies, which they believe spy for the West.  But this seems an inadequate explanation taking account of the huge need for humanitarian assistance.

Possibly, the separatists are more worried about credible, independent witnesses to what they expect to be increased suffering as winter approaches.  According to recent polls in separatist-held areas, the separatists have become increasingly unpopular.  As fall elections approach, they may have calculated that they can still manipulate the elections enough to show strong support if they can limit information about discontent and conduct the elections on their own terms instead of according to the terms of the Minsk agreement.  The less bad news the better.
