In western town of Duekoue UN forces are attempting to protect thousands of civilians taking shelter in a church compound.
Hundreds of people were reportedly killed in the town following fighting last week.
Forces loyal to internationally recognised president Alassane Outtara have been accused of being behind the killings, but officials of Mr Ouattara's government deny this.
BBC Network Africa's Paul Bakibinga spoke to Guillaume Ngefa, Deputy Director for Human Rights in the UN mission in Ivory Coast.
