William O'Neill, the UN Haitian human rights expert, warned on Friday that gang violence is spreading in the Caribbean country.

A U.N. human rights expert says that gang violence is spreading across Haiti as a U.N.-backed mission targeting criminals remains underfunded and understaffed.

The United Nations' expert on human rights in Haiti said on Friday that the situation in the conflict-hit Caribbean nation had worsened and efforts to rebuild security must be amplified as a security mission deadline fast approaches.

A UN expert says Haiti is in a "race against time," as gangs' control over the capital and the massive displacement of the population deepens the country's crisis.
