As reported earlier on Arutz Sheva, a gunman has taken 20 Ukraine bus passengers hostage.
The BBC notes that the man is presumed mentally ill.
Police are at the scene, in the city of Lutsk, and are attempting to talk to the man and resolve the crisis.
Apparently, the man is demanding that certain senior Ukrainian politicians admit to being terrorists.
Police have cordoned off the city center and residents have been told not to venture outside. So far, there are no reports of any injuries.
