New York-based lobby group Human Rights Watch has urged Sierra Leone's authorities to find those who killed a leading gay rights activist.
FannyAnn Eddy told the UN that homophobic attacks go unpunished
FannyAnn Eddy, 30, was strangled by people who broke into her office.
Earlier this year, she told a UN conference that gays and lesbians faced "constant harassment and violence" in Sierra Leone.
She founded the Sierra Leone Lesbian and Gay Association in 2002.
Homosexual acts are illegal in Sierra Leone, according to Amnesty International.
"FannyAnn Eddy was a person of extraordinary bravery and integrity, who literally put her life on the line for human rights," said Scott Long, director of the Lesbian, Gay, Bisexual and Transgender Rights Project at Human Rights Watch.
"Homophobic attacks go unpunished by authorities, further encouraging their discriminatory and violent treatment of lesbian, gay, bisexual and transgender people," Ms Eddy told the UN Human Rights Commission in Geneva.
"The authorities in Sierra Leone must investigate this crime fairly and fully," said Mr Long.
"They must send a message to a frightened lesbian and gay community that violence against them will not go unpunished."
