CAIRO — At least 34 people have been arrested in Egypt as part of an expanding crackdown on the gay and transgender community following a rock concert last month when audience members waved a rainbow flag.
The crackdown has been fueled by social media, where images of the flag-waving were widely shared, and by dating apps and other websites, which the Egyptian police have used to entrap people suspected of being gay and transgender, activists and officials say.
