4 detained during massive pro-EU protest in Poland

WARSAW, Poland (AP) — Police in Warsaw say four people, including a nephew of the prime minister, were detained during a massive protest against government policy that critics say could cost Poland its European Union membership. Organizers and city authorities say up to 100,000 people took part in the protest in Warsaw on Sunday. Similar protests were held in many other Polish cities. They were sparked by a top court’s ruling that the Polish constitution has supremacy over EU law. The case was initiated by the prime minister. Critics say the court ruling can be seen as rejection of EU values and may potentially lead to “Polexit” or the nation being forced out of the 27-member bloc.
