At least 110 mostly elderly people have been murdered by gang members in the Haitian capital, Port-au-Prince.

The National Human Rights Defence Network said a local gang leader had targeted them after his son fell ill and subsequently died.

The gang leader reportedly consulted a voodoo priest who blamed elderly locals practising “witchcraft” for the boy’s mystery illness.

The UN said the number of people killed in Haiti so far this year in spiralling gang violence had reached “a staggering 5,000”.
