Ten men have been arrested on suspicion of being gay on the Tanzanian island of Zanzibar after police received a “tip-off” from members of the public about a same-sex marriage taking place, Amnesty International has revealed. The arrests come after a prominent Tanzanian politician last week called on the public to report the names of suspected gay men to the police – comments subsequently denounced by the government. “This is a shocking blow following the Tanzanian government’s assurance that no one would be targeted and arrested because of their actual or perceived sexual orientation and gender identity,” said Seif Magango, Amnesty International’s Deputy Director for East Africa, the Horn and the Great Lakes.
