Amnesty International says leading Haitian human rights activist threatened over his work

Amnesty International says a leading human rights activist in Haiti has been threatened for his work.

The watchdog group said Tuesday that Pierre Esperance received a threatening letter at his organization's office earlier this month, along with a bullet.

The letter accused the executive director of the National Human Rights Defense Network of publishing false reports aimed at destabilizing the government of President Michel Martelly. It also mentioned an earlier attack on Esperance when he survived bullet wounds to the shoulder and knee.

The note's writers said they missed him in 1999, but he won't escape a future attack.

The alleged threat is the latest aimed at Haiti's human rights advocates.

An activist and his wife were gunned down in Port-au-Prince in February. The case is still under investigation.
