At least 120 demonstrators were killed by the security forces in Ivory Coast in March, according to a UN report. Several hundred others were said to be injured when the security forces opened fire on the demonstrators - 20 are still believed to be missing. "What happened on 25 and 26 March was the committing of massive human rights violations," the report said. The clashes put further strain on the peace deal between northern-based rebels and the government in the south.
