According to Nigerian law, a heterosexual ally "who administers, witnesses, abets or aids" any form of gender non-conforming and homosexual activity could receive a 10-year jail sentence. In addition to criminalizing homosexuality, Nigeria has enacted legislation that would make it illegal for heterosexual family members, allies and friends of LGBT people to be supportive. In Uganda, Tanzania, and Sierra Leone, offenders can receive life imprisonment for homosexual acts, although the law is not enforced in Sierra Leone. In Somalia, Somaliland, Mauritania and northern Nigeria, homosexuality is punishable by death. Nevertheless, most scholarship and research demonstrates that homosexuality has long been a part of various African cultures. Past African leaders such as Zimbabwe’s Robert Mugabe and Uganda’s Yoweri Museveni claimed that LGBT behaviour was brought into the continent from other parts of the world. In spite of this, many African countries have refused to consider increasing LGBT rights, and in some cases have drafted laws to increase sanctions against LGBT people. Since 2011, some developed countries have been considering or implementing laws that limit or prohibit general budget support to countries that restrict the rights of LGBT people. LGBT anti-discrimination laws exist in seven African countries: Angola, Botswana, Cape Verde, Mauritius, Mozambique, Seychelles, and South Africa. South Africa was the fifth country in the world to legalize same-sex marriage in November of 2006. It has been decriminalised in Angola, Botswana, Cape Verde, Gabon, Guinea-Bissau, Lesotho, Mozambique, São Tomé and Príncipe, the Seychelles and South Africa. Homosexuality has never been criminalised in Benin, Burkina Faso, Ivory Coast, Democratic Republic of the Congo, Djibouti, Equatorial Guinea, Madagascar, Mali, Niger, and Rwanda. Human Rights Watch notes that another two countries, Benin and the Central African Republic, do not outlaw homosexuality, but have certain laws which discriminate against homosexual individuals. Out of the 54 states recognised by the United Nations or African Union or both, the International Gay and Lesbian Association stated in 2015 that homosexuality is outlawed in 34 African countries. With the exception of South Africa and Cape Verde, lesbian, gay, bisexual, and transgender ( LGBT) rights in Africa are limited in comparison to the United States, Canada, Western Europe, Australia, and New Zealand. Same-sex marriage constitutionally banned in 9 out of 54 countries Allowed to serve openly in 1 out of 54 countries
