Afterwards, Jacek Dobrzynski, spokesperson for Poland's minister-coordinator of special services, said the threat is being treated as deadly serious, with a strong chance it could actually happen.
That's everything we know.
Why this mattersSo who are we talking about?
Donald Tusk runs the country. Wladyslaw Kosiniak-Kamysz is his deputy and runs the military. Both in Poland. A NATO country. An EU country.
No suspect has been named. Nobody has said how the threat was sent.
But Polish media are filling in some gaps the security services haven't confirmed.
Radio Zet says police got an email with the threat inside it.
Gazeta Wyborcza goes further. It says the threat came through electronic channels, and it named the politicians' homes and their plans for the coming days.
Neither claim has been confirmed by the security services themselves.
Adam Szlapka, the government's spokesperson, told Polsat News the matter is serious. He said Tusk was briefed this morning, and that Tusk has stayed in Warsaw and is carrying on with his normal work. Szlapka said more details will come once the services can release them.
Tusk and Kosiniak-Kamysz haven't said a word about it themselves.
And here's something Dobrzynski added. He said threats like this against Poland's police and security services have been climbing year by year.
Now the timing.
This threat lands in the middle of a brutal week in Poland. Four days ago, a 19-year-old injured nine people at a school in Ostroleka. The next day, a 15-year-old fatally stabbed a school employee near Wyszkow. The day after that, a woman injured three people in a knife attack at a school in Warsaw.
Tusk has called it a cult of violence. He says Poland is seeing more fascination with violence, in Poland and worldwide. He says there's no evidence of one big organised group behind it, though some of those detained have ties to far-right circles.
Poland's Interior Minister, Marcin Kierwinski, says there's no evidence the three school attacks are linked to each other, or to any online challenge pushing kids toward violence.
Nobody has said whether the threat against Tusk and Kosiniak-Kamysz connects to any of that, or stands completely apart from it.
Separately, Poland's security services have detained eight people suspected of scouting and sabotage against military sites and critical infrastructure.
So three questions are sitting wide open right now. Where did this threat come from? Has anyone been identified? And is any of this connected, or are these just three dangerous things happening in Poland at the same time?
