Criminal statutes banning homosexuality are on the books in 70 countries, according to the International Lesbian, Gay, Bisexual, Trans and Intersex Association (ILGA).
The big picture: Homosexual acts are outlawed in many Muslim countries as well as former British colonies, including 32 African countries. On Tuesday, Botswana's top court voted to decriminalize same-sex relationships, and Angola, Mozambique and Seychelles have made similar moves in recent months. In May, Taiwan became the first Asian country to legalize same-sex marriage.
