Polish police say they arrested 210 people during Independence Day marches that turned violent, and that nearly half of them were Germans.
Police spokesman Maciej Karczynski said Saturday that 92 Germans were among those arrested after youths began attacking police with bottles, cobblestones and other objects during Friday's marches. Also arrested were a Spaniard, a Hungarian and a Dane.
He also said that 40 police officers were injured and 14 police cars destroyed.
Prime Minister Donald Tusk was holding a special meeting with key security officials, including the interior and justice ministers, to consult on what turned out to be some of the worst street violence in Poland in years.
