(Newser) – A Polish man has been arrested for allegedly plotting to detonate a four-ton bomb in front of the country's parliament amid a budgetary debate. The BBC reports that the academic researcher, 45, has confessed to planning the assassination of the president and other leaders. Prosecutors called the unnamed man's motives "nationalistic, xenophobic, and anti-Semitic." Videos show him testing explosives in his home, officials say. He's also accused of trying to recruit allies; two others have been arrested for possession of illegal firearms.

An interesting detail, per the AP: The country's PM says the suspect and his plot were discovered as investigators looked into Polish links to Norwegian mass murderer Anders Behring Breivik. Polish security officials have said that Breivik bought small amounts of material for his bomb-making in Poland. (Read more Poland stories.)
