Police have allegedly arrested ten gay men on the island of Zanzibar in Tanzania after the government ordered a crackdown on the LGBT community. Authorities in the country raided a gathering of people celebrating a same-sex wedding while some were able to flee, ten were taken into custody. Amnesty International fears that these men may be subject forced anal examinations—a medical practice used to “prove” if a man’s homosexual.

Earlier this month, the government of the country’s largest city, Dar es Salaam said that it planned on arresting “every homosexual” in city.

“It is mind-boggling that the mere act of sitting in a pair can assume criminal proportions” said Seif Magongo of Amnesty International. “The police clearly have no grounds to file charges against these men in court, despite arresting them three days ago.”
