UN Secretary General Ban Ki-moon has urged African leaders to respect the rights of gay, lesbian, bisexual and transgender people.
Speaking at the opening of the 18th African Union (AU) Summit in Addis Ababa, Ethiopia, Ban told leaders:
'One form of discrimination ignored or even sanctioned by many states for too long has been discrimination based on sexual orientation or gender identity.
'It prompted governments to treat people as second class citizens or even criminals.'
