Amsterdam is marking 25 years since the world's first gay marriages were celebrated in the Netherlands. Three couples married at City Hall on Wednesday just after midnight, led in a ceremony by Mayor Femke Halsema. More than 40 countries now allow same-sex marriages. Dutch Prime Minister Rob Jetten, who is gay, says the milestone inspired him as a teenager. The LGBTQ movement is facing challenges elsewhere. Advocates cite new efforts in some U.S. states to challenge marriage equality and rising hostility toward LGBTQ+ people in parts of Africa.
