JAKARTA, Indonesia — Dozens of men, including several foreigners, were arrested in a raid of a gay sauna in Indonesia’s capital, police said Sunday, as lesbian, gay, bisexual and transgender people face increased hostility in the world’s most-populous Muslim nation. Police spokesman Argo Yuwono said Friday’s raid in downtown Jakarta will lead to seven people being charged under Indonesia’s pornography law, including the sauna’s owner and staffers.
