Pole held in plot to bomb Parliament

WARSAW— A Polish university researcher driven by nationalistic and anti-Semitic hatred was arrested for planning to detonate a 4-ton bomb in front of the Parliament building in Warsaw with the president, prime minister, government ministers, and lawmakers inside, authorities said Tuesday.

Prime Minister Donald Tusk said the suspect and his plot were discovered as investigators looked into Polish links to the Norwegian mass murderer Anders Behring Breivik. Polish security officials have said that Breivik bought small amounts of material for his bomb-making in Poland.

The foiled attack comes as the far-right movement appears to be growing in Poland, and as tensions simmer between Tusk’s center-right government and its main rival, the conservative Law and Justice party led by Jaroslaw Kaczynski.

Kaczynski recently accused Tusk and other leaders of murder in the 2010 plane crash that killed his brother, the late President Lech Kaczynski, and 95 others. A state investigation found the tragedy was an accident caused by bad weather and human error, but Kaczynski has been calling it an assassination.

Tusk said the dramatic plan to assassinate Poland’s leaders shows that it is ‘‘high time to abandon a language of violence and hatred in public debate.’’

Prosecutors said Tuesday that they arrested the suspect in Krakow on Nov. 9. They said he is a 45-year-old Polish researcher employed at the University of Agriculture in Krakow who had access to chemistry laboratories.

He illegally possessed explosive materials, munitions, and guns.

They said the suspect was motivated by nationalistic, xenophobic, and anti-Semitic ideas.
