PRAGUE — Thousands rallied in the Czech capital Wednesday to honor two Slovak gay men shot dead this month outside a bar in Slovakia, and demanded better protection of LGBTQ people and their families. The gathering in Prague’s central Wenceslas Square was held the same day the funerals of Matúš Horváth and Juraj Vankulič were conducted in Slovakia. Police said they boosted their presence at the Prague rally after they detained a man who was threatening to use a gun against the LGBTQ people at the square.
