WARSAW, Poland (AP) — A fake news report that appeared on Poland’s national news agency saying that Prime Minister Donald Tusk was mobilizing 200,000 men starting on July 1 was probably the work of Russia-sponsored hackers and was designed to interfere with the upcoming European Parliament election, authorities said.

“Everything indicates that we are dealing with a cyberattack directed from the Russian side,” said Krzysztof Gawkowski, a deputy prime minister who also holds the digital affairs portfolio. “The goal is disinformation ahead of (European Parliament) elections and a paralysis of the society.”

Tusk said on X that it was “Another very dangerous hacker attack which well illustrates Russia’s destabilization strategy on the eve of the European elections. ... It is increasingly clear how important these elections are for us.”
