Poland’s defence minister has asked the security services to investigate how hundreds, or even thousands, of soldiers and civilian employees of the army received harassing telephone calls from Russia.
The number of people who got mysterious calls from Russia has been reported to be as high as 10,000.
Tomasz Siemoniak, the defence minister, said the exact total had not yet been established, but it could “be hundreds or thousands”.
“The security services brought the matter to my attention and I have asked for clarification,” added Mr Siemoniak. “At the moment it is difficult to say as if this was something serious or not.”
