The United States has criticized a West African leader's threat to slit the throats of gay men and said that it was considering sanctions.

Gambian President Yahya Jammeh was quoted by Vice News making the threat during a rally earlier this month in the town of Farafeni.

“If you do it [in Gambia], I will slit your throat,” Jammeh said. “If you are a man and want to marry another man in this country and we catch you, no one will ever set eyes on you again, and no white person can do anything about it.”

In a statement given to the Washington Blade, National Security Advisor Susan Rice called the comments “unconscionable.”

“The recent unconscionable comments by Gambian President Yahya Jammeh underscore why we must continue to seek a world in which no one lives in fear of violence or persecution because of who they are or whom they love,” she said.

Rice's comments, made Saturday, included a reference to the International Day Against Homophobia and Transphobia (IDAHOT), observed annually on May 17.

“Tomorrow, the international community will mark the International Day Against Homophobia and Transphobia. This day and every day, the United States stands in solidarity with members of the lesbian, gay, bisexual, and transgender (LGBT) community and all those around the world who work to advance the unassailable principle that LGBT rights are human rights.”

Earlier this week, the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, and the Robert F. Kennedy Center for Justice & Human Rights joined in calling for the White House to condemn Jammeh's remarks and increase sanctions against The Gambia, including travel restrictions for the nation's top political leaders.

Rice said that the United States in 2014 ended trade preferences with The Gambia in response to human rights violations.

“[W]e are reviewing what additional actions are appropriate to respond to this worsening situation,” she added.
