Poland in Panic as Army Officers Receive Mysterious Phone Calls From Russia

Polish security services are investigating after military employees using one of the country's phone carriers received mysterious calls from Russia.

"Someone in Russia" reportedly called 10,000 soldiers and military employees in Poland, the country's defense ministry told Nasz Dziennik.

The calls were linked to a Russian telephone services operator, where subscribers would pay a pemium for calling back a number. Although the incident appears to have been a commercial scam, Poland's counterintelligence is investigating the issue as a matter of national security.

"This type of call also reached certain number of subscribers unconnected with the military. All phones belong to the Plus network, which is operated by Polkomtel," the Nasz Dziennik report said.

Investigators are now looking for the source of the phone number leak, which has led to the calls, dubbed an "attack on an army base" in Polish media. Calling the number back may have incurred high fees for phone users, according to the report.

Poland has numerous mobile phone operators, only one of which was reportedly affected by the apparent fraudulent calls considered a threat to national security.
