Polish deputy foreign minister says Navalny situation very worrying -PAP

The situation surrounding Russian opposition politician Alexei Navalny is very worrying and there should be an international investigation, Polish Deputy Foreign Minister Marcin Przydacz told state-run news agency PAP on Wednesday.

Navalny, who is in intensive care in a Berlin hospital, was poisoned with a Soviet-style Novichok nerve agent in an attempt to murder him, German Chancellor Angela Merkel said on Wednesday.

"Poland's position is clear. We believe that an explanation is necessary cases and punishment of the guilty. We call for an international investigation," PAP quoted Przydacz as saying.
