LGBT activists held a central Polish city’s first pride parade without incident Saturday amid a deep divide in the country over gay and lesbian rights. The parade in Plock, about 100 kilometers (60 miles) west of Warsaw, came three weeks after anti-gay violence marred the first pride march in the eastern city of Bialystok. Far-right radicals attacked march participants with rocks, glass bottles and firecrackers on July 20, causing injuries and riot police to intervene. In Plock on Saturday, about 2,500 parade participants, many carrying rainbow flags, walked through the city unmolested. They were surrounded by a large number of police officers, a sign authorities were determined to prevent a repetition of last month’s violence. The pride events took place amid a backlash against an LGBT movement that is growing more visible in the predominantly Catholic country.
