The United Nations is demanding an immediate investigation into reports forces loyal to Ivory Coast’s President Allesane Ouattara have been attacking supporters of his predecessor.
Human Rights Watch claims 150 people have been killed since Ouattara came to power.
The UN referred particularly to reports of an elderly man dying in Yakassé-mé and machete attacks in Domolon.
There had already been reports of human rights abuses on both sides as the country plunged into six months of civil war following Laurent Gbagbo’s refusal to accept defeat in last year’s presidential vote.
Around 3,000 died in the conflict. Outtara called for national unity when he was finally sworn in.
