Haiti is on the “verge of the abyss”, according to the UN, as heavily armed gangs expand their control of the country. Armed groups control – and terrorise – at least 60% of the capital Port-au-Prince and its surroundings, according to Haitian human rights groups. They are also warning rape is increasingly being used as a weapon. In the first six months of this year, the gangs killed almost 1,000 people, the UN has said.
