I'd heard that it was the countries people were trying to enter, like Poland, that were causing the problems - but then, there's a lot of info. and counter-info. out there at the moment, so it can be difficult to know the details. I know Indian ministers have travelled to Ukraine's various borders to ensure their citizens (who were also facing racism) get through OK, and hopefully the international attention on this will mean things run more smoothly (and less racist-ly) from here on out.
