Map: Where it's illegal to be gay around the world

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.
