ISTANBUL: Turkish riot police in Istanbul on Sunday fired tear gas and rubber bullets to disperse protesters defying a ban on the city’s Gay Pride parade. Authorities in Turkey’s biggest city banned the annual parade earlier this month over security concerns, sparking anger from gay rights activists. Two German politicians—Volker Beck, a prominent Green lawmaker and one of Germany’s most vocal gay politicians, and Green MEP Terry Reintke—were detained briefly, each said on Twitter. Police at the scene—who heavily outnumbered demonstrators—said 12 people had been detained, an Agence France-Presse photographer said. About 300 young protesters turned out despite the ban on the parade, which rights activists have been staging in Istanbul for the last 12 years.
